I did upgrade to last version of Q2A and Php
the issue is that clicking any plugin option the website load for a long time then it become
offline for a while
My server support did their best to resolve the issue but without any result
we tried many things like removing any plugins appear in the apache error log file
And the last experiment was increasing the max execution time for PHP is set to 1000s for web servers but still the script timeout occurs.
then the support sever provider ask if they need any more settings changed for it to work
How to resolve the issue
