I Updated my virtual server with new cpanel and apache and now 4 websites come up with this error:
Fatal error: Class 'mysqli' not found in /home/ecopaws/public_html/system/library/db/[url removed, login to view] on line 7
A domain example is here: [url removed, login to view]
I have tried to restore the back up but not working.
My virtual server is:
Operating System: CentOS 6.7
Platform: VMware vSphere 5.5.0
Control Panel: cPanel and WHM [url removed, login to view]
