Dear authorized friends.
I have waited too long for you to find the error. I am short of time. I have to work on my site. If you will not be interested in finding the error. I can restore my site and continue. Please, I am waiting for a valid answer or result.
Hello Hung PD
The problem persists. We are running out of time to fix this error. I want you to find the source of the error and tell me. I have a backup of my site, I can restore it and continue. Please find the problem, even if you don’t fix it, just tell me the source.
It’s strange. You should deactivate all plugins (except Required Plugins) and then reactivate them one by one. This makes it very easy to isolate the plugin causing problems.
Also, please undo the changes you made or please let me know what the changes?
