After standard installation of phpmyadmin on Ubuntu 14.04 I found <site>/phpmyadmin doesn't work. After googling it, I found this can be solved with adding this line

Include "/etc/apache2/conf-enabled/*.conf"

Added to /etc/apache2/apache2.conf config file.

But after apache reload I get this error message

 * Reloading web server apache2
 * 
 * The apache2 configtest failed. Not doing anything.
Output of config test was:
AH00526: Syntax error on line 30 of /etc/apache2/conf-enabled/phpmyadmin.conf:
Unknown Authz provider: valid-user
Action 'configtest' failed.
The Apache error log may have more information.

How can I fix error and make phpmyadmin working?

  • What's "standard installation" mean here -- did you use the packaged (dpkg/apt/aptitude/etc) version or download the source from phpMyAdmin and uncompress it to your web root? – ibennetch Nov 22 '15 at 15:55

It seems that the module 'mod_authz_user' is not enabled. You can use a2enmod to enable it for your apache installation.

sudo a2enmod authz_user

It will now tell you that is has been activated and that you need to restart your apache instance. In Ubuntu 14.04 this can be done as follows:

sudo service apache2 restart

Had the same Problem. What fixed it was putting a "-" between valid and user, like that: valid-user.

I just ran into the same problem ... after replacing a failed harddisk in mdraid and restarting the server in that process Apache failed to start with the same error message:

AH00526: Syntax error on line 30 of /etc/apache2/conf-enabled/phpmyadmin.conf:
Unknown Authz provider: valid-user

But the module authz_user was already loaded. As it turned out the problem was something completely different.

Running sudo apache2ctl -M showed a different error:

AH00526: Syntax error on line 7 of /etc/apache2/sites-enabled/net.example.ghost.conf:
Invalid command '<Proxy', perhaps misspelled or defined by a module not included in the server configuration
Action '-M' failed.

I had to enable a couple of modules and run sudo apache2ctl -M again until all necessary modules were loaded. After that, Apache started without problems, and without any changes in /etc/apache2/conf-enabled/phpmyadmin.conf.

You need to edit phpmyadmin config file /etc/apache2/conf-enabled/phpmyadmin.conf and remove line (30 in my case) Authz provider: valid-user. Save it. Apache should now reload normally, and phpmyadmin should work now.

    You just removed the requirement that a user be verified before accessing whatever... just FWIW. – dyasta Dec 30 '16 at 01:40

I put V capitalized in valid-user in my case. I recommend you check If you have the same case .

the route is /usr/share/phpmyadmin/.htaccess

    It is unlikely that editing an htaccess file will resolve an error in `/etc/apache2/conf-enabled/phpmyadmin.conf` .... – HBruijn Jan 25 '16 at 06:27
