Thanks for all the help but still there is some issue. When I upgraded after removing adsense plugin it worked on my device but I received many mails from our users that site is not working.
I check on multiple devices and realize that its working for few but not in others.
If you open IP address directly it works fine, but when website url is entered it does not show anything on devices with issue.
I have already tried deleting cache and temporary files from systems. It did not worked.
If I see error logs this is the common warning
What can be the possible cause for this and what should I do.
Note: I have already removed all plugins, only tag (offical) plugin is installed at the moment.
