Hello @ipghmagnet,
i would restore the website to the previous version using the backup you may have before the update process and share with us from which version of Elxis have you updated to 5.2 one.

Updated:
As i read a private message you have upgraded from 4.5 version. Have you followed these instructions by applying this patch?

I replied to your PM. It is due to one of your third party plugins. Update them. If this doesn't fix the problem unpublish the plugins one by one to find out which one causes the problem. If you can;t fix the problem send me a personal message with username/password for your site's administration to fix it for you.

Dear Datahell,

Thanks for your kind help.

I do as you said. I found "addthis" plugin is in problem and " qr code" is also in problem.

Now I unpublished all plugines.

I got my website back. 

In future, I will use less plugines. 

Thanks a lot.
