I have no idea who is, just got the login data and a friend who owns the site and tells me he can’t reach anyone. At weekends not at all and only in the evening on Monday, Tuesday etc… We had another [solved] problem with the website some days ago, and there was no help at all, too. I’m in fact just the one who tries to repair WP and has to deal with the given issues…
So I try to do my best in fixing the problem without error-log or at least without the website’s host.
