I get this error when I switched my Drupal from IIS7 to Apache 2.2.15.
With IIS-7 - it runs fine,
When I switch to Apache I get the above error.
I didn't change the code in my php.ini - currently:
The file mysqli.dll does exists on the server.
And I've googled for a solution but get all the same responses, to check the php.ini or httpd.conf file - but it runs fine under IIS-7
Please advise a solution?
