Some errors have been detected on the server, please look at the bottom of this window.

You might have already worked in phpMyAdmin. PHP 7 or newer version, when you click any table or columns in phpMyAdmin, you might get pop-up error message "Some errors have been detected on the server, please look at the bottom of this window." This error caused phpMyAdmin not compatibility with PHP 7.2 or newer version.

You can fix this issue with small change in the file /usr/share/phpmyadmin/libraries/sql.lib.php. First, backup sql.lib.php before editing with below command.

sudo cp /usr/share/phpmyadmin/libraries/sql.lib.php /usr/share/phpmyadmin/libraries/sql.lib.php.backup

Now edit sql.lib.php file using nano command.

sudo nano /usr/share/phpmyadmin/libraries/sql.lib.php

Press CTRL + W and find the line

(count($analyzed_sql_results['select_expr'] == 1)

And replace it with:

((count($analyzed_sql_results['select_expr']) == 1)

Press CTRL + X, and then SHIFT + Y and then press ENTER. That's it. The error should have gone.

There is also one other method to ignore the errors in phpMyAdmin.

Open the /etc/phpmyadmin/config.inc.php file in nano editor.

sudo nano /etc/phpmyadmin/config.inc.php

And add the below lines at the end of file

$cfg['SendErrorReports'] = 'never';

Save file and exit. This will ignore and hide all errors in phpMyAdmin.
