I have tried replacing count($analyzed_sql_results['select_expr'] == 1) with (count($analyzed_sql_results['select_expr']) == 1) in /usr/share/phpmyadmin/libraries/sql.lib.php file. but still no success.

Answer 1

In line 551 /usr/share/phpmyadmin/libraries/plugin_interface.lib.php just replace the

if($options != null && count($options) > 0){

with

if ($options != null && (is_array($options) || $options instanceof Countable) && count($options) > 0) {
