Hi 67072568252,

Do you remember making any changes to the site before the error started?

I recommend checking your PHP error log to see what the full error is. The error log may be available in your web host control panel. If you can't find it, contact your web host support.

Hello and thanks for the reply.
I was editing site breadcrumbs and then this happens, even backup restoration does not seem to fix the problem. I'm really worried about this. :/

Think you guess that refers to a server-side problem?

Your guess was right.Reason is server side some weird problem.No accurate information about cause of the error. Might doubt some time ago made php 7 update?

-- The main thing is that site works again.
