PHPMyAdmin – count(): Parameter must be an array or an object that implements Countable

Edit file /usr/share/phpmyadmin/libraries/sql.lib.php:

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

On line 613 the count function always evaluates to true since there is no closing parenthesis after $analyzed_sql_results['select_expr']. Making the below replacements resolves this, then you will need to delete the last closing parenthesis on line 614, as it’s now an extra parenthesis.

Replace:

((empty($analyzed_sql_results['select_expr']))
|| (count($analyzed_sql_results['select_expr'] == 1)
&& ($analyzed_sql_results['select_expr'][0] == '*')))

With:

((empty($analyzed_sql_results['select_expr']))
|| (count($analyzed_sql_results['select_expr']) == 1)
&& ($analyzed_sql_results['select_expr'][0] == '*'))

Restart the server apache:

sudo service apache2 restart
