FatalExceptionError in PDOconnection line 70 when trying to login to BO

Hi,

Don't know what happened and what impacted the backoffice functionality, tried logging in today and saw Error 500, enabled debugging and saw this error, any one else facing similar issue or have suggestion to fix the problem?

I am using Prestashop 1.7.8.6 version with PHP 8.0 on the webserver.

At first change your PHP version to 7.4

Thanks! that worked after bringing the php version down to 7.4

I also had to make following changes in the php.ini file:

session.save_path = /tmp

max_execution_time =600

max_input_time = 600

max_input_vars = 7000

memory_limit = 256M
