Issue Plesk Obsidian 18.0.29 - MySQLi is not working

[EternexSystems]

My server currently updated to Plesk Obsidian 18.0.29 now I created a website, with no issues with PHP however all attempts to connect to a database using the PHP MySQli extension failed miserably... PDO apppears to work, but all my code is written with MySQli... refactoring is not option. Can someone help...??

MySQLi module is loaded by default for Plesk PHP versions at least. For PHP 7.4, for example:

# /opt/plesk/php/7.4/bin/php -m | grep mysqli
mysqli

Make sure that you have loaded this module for PHP version that you are using.

I am using PHP 7.2 thought mysqli will be loaded by default... so do you mean I should execute that line with SSH...???

 

[EternexSystems]

I just checked my settings now... mysqli is enabled...

What exact error message do you have? How this issue can be reproduced? Could you please be more specific?

 

[EternexSystems]

Yes that's the thing... mysqli just doesn't execute... it returns no error message either with mysqli_error($conn) or $conn->connect_error()... so I personally have no idea what I'm doing wrong or what's happening....
