XAMPP phpMyAdmin not accessible in Windows

Unable to access phpMyAdmin on XAMPP (in Windows)

XAMPP is a great tool for web developers because it packages a couple of applications used for web hosting into one program, and it allows websites to be tested locally on a computer. Unfortunately, because it links multiple applications together, it is pretty error-prone.

One of the errors that might happen is that you might not be able to access XAMPP’s phpMyAdmin, which provides users with an interface to modify the local SQL database. In this article, we go through the various reasons why this might occur, as well as how you can fix them.

  1. Possible causes
    1. You didn’t start MySQL on XAMPP
    2. You changed XAMPP’s default MySQL login credentials
    3. ‘localhost’ not allowed to connect
    4. Port 3306 is occupied
  2. Conclusion

1. Possible causes

a. You didn’t start MySQL on XAMPP

If you see a screenshot like that when you access phpMyAdmin, then it’s likely because you didn’t start MySQL on XAMPP. Go start it and try again!

phpMyAdmin connection refused
phpMyAdmin cannot be connected to without starting MySQL.

b. You changed XAMPP’s default MySQL login credentials

If you see something like this, that means that you might have changed XAMPP MySQL’s default login credentials:

Access denied phpMyAdmin
Access to phpMyAdmin denied.

For phpMyAdmin to work, it has to interface with MySQL using a set of login credentials. By default, the login credentials for XAMPP’s MySQL is root with no password. If you have tinkered with MySQL on your machine previously, you might have updated MySQL’s root login credentials.

If you remember or know the updated login credentials, and have installed XAMPP in the default installation directory, you can find it at C:\xampp\phpMyAdmin\config.inc.php. The lines highlighted below are the ones you want to update:


 * This is needed for cookie based authentication to encrypt password in
 * cookie
$cfg['blowfish_secret'] = 'xampp'; /* YOU SHOULD CHANGE THIS FOR A MORE SECURE COOKIE AUTH! */

 * Servers configuration
$i = 0;

$cfg['Servers'][$i]['central_columns'] = 'pma__central_columns';
$cfg['Servers'][$i]['designer_settings'] = 'pma__designer_settings';
$cfg['Servers'][$i]['export_templates'] = 'pma__export_templates';
$cfg['Servers'][$i]['favorite'] = 'pma__favorite';

 * End of servers configuration

Otherwise, you are going to have to uninstall and reinstall XAMPP. Before you do that however, make sure that your computer does not have any other MySQL applications running, as they can interfere with the normal functioning of XAMPP.

c. ‘localhost’ not allowed to connect

If you see something like this, then it is possible that your MySQL user table has corrupted data.

'localhost' not allowed to connect to MariaDB
You’ll have to repair your MySQL user table.

In such a case, you have to log in to phpMyAdmin to repair the table. To do so, follow the steps below:

  1. First, you’ll need to update your MySQL configuration so that you can get into phpMyAdmin. Access my.cnf by clicking on Config → my.ini.
Where to find MySQL's my.cnf

  1. Next, you’ll need to add skip-grant-tables under the [mysqld] section:


# Example MySQL config file for small systems.
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
# You can copy this file to
# C:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
# password       = your_password 

# Here follows entries for some specific programs 

# The MySQL server
# enable-named-pipe

# Change here for bind listening
# bind-address="" 
# bind-address = ::1          # for ipv6

# Where do all the plugins live

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
# log-bin deactivated by default since XAMPP 1.4.11

# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id	=1

# Replication Slave (comment out master section to use this)
# To configure this host as a replication slave, you can choose between
# two methods :
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#    Example:
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
# OR
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
# The replication master for this slave - required
#master-host     =   <hostname>
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
# binary logging - not required for slaves, but recommended

# Point the following paths to different dedicated disks
#tmpdir = "C:/xampp/tmp"
#log-update = /path-to-dedicated-directory/hostname

# Uncomment the following if you are using BDB tables
#bdb_cache_size = 4M
#bdb_max_lock = 10000

# Comment the following if you are using InnoDB tables
#innodb_log_arch_dir = "C:/xampp/mysql/data"
## You can set .._buffer_pool_size up to 50 - 80 %
## of RAM but beware of setting memory usage too high
## Set .._log_file_size to 25 % of buffer pool size

## UTF 8 Settings
#init-connect=\'SET NAMES utf8\'


# Remove the next comment character if you are not familiar with SQL



  1. This will allow you to access phpMyAdmin from http://localhost/phpMyAdmin. While in there, you will want to access the mysql database, and check the user table. Then, select the Repair table option on the dropdown. Refer to the image below:
phpMyAdmin repair user table
Once you select the Repair table option, phpMyAdmin should execute an SQL query to repair the table.

d. Port 3306 is occupied

Usually, when port 3306 is occupied, you will not even be able to start MySQL on XAMPP. In rare cases, however, MySQL will actually start with a warning:

XAMPP MySQL starts with port 3306 occupied.
XAMPP MySQL starts with port 3306 occupied.

This will not only leave you unable to access phpMyAdmin. You will not be able to access any website on XAMPP that needs a database connection as well.

To rectify this problem, you will need to find the program that is currently blocking or using port 3306, and stop the program. In such a case, XAMPP will pinpoint the program for you:

11:09:49 pm  [mysql] 	Port 3306 in use by "C:\Users\terre\AppData\Local\Programs\Python\Python312\python.exe"!
11:09:49 pm  [mysql] 	MySQL WILL NOT start without the configured ports free!
11:09:49 pm  [mysql] 	You need to uninstall/disable/reconfigure the blocking application
11:09:49 pm  [mysql] 	or reconfigure MySQL and the Control Panel to listen on a different port

2. Conclusion

If you have an error that is not covered in this article, do let us know in the comments below. We will like to document these different scenarios where phpMyAdmin doesn’t work, so that this document can be a time-saver for developers all over the world.

  1. After the last windows 11 update I’ve found two issues:
    1. Do not start the index.php. The browser is waiting for the initial page
    2. By clicking on “phpMyAdmin” also in this case the browser is waiting and I do not have access to the DB

    Both Apache and MySQL are green and no error is shown.

    Did someone have the same problem and found a solution?
