Nothing changed.
I checked the database but it seems as if there are all tables correct.
And I tried to make a second install (different database, different folder) with 1.34 but there I did not get the offer to update the copied database... it overwrite all and clear the database.

I did but no change... the same error like before. Can it be a problem by changeing the URL? But in all places there is a relative path... or did I forget something?

The same error like before after I tried the other "LocalSetting". The "DefaultSettings" I did not change because there was nothing I had to change in it...

If this is the only problem, it should be enough to take the original LocalSettings from the upgrade-package and add the nessesary informations... I hope it is so easy.

Server API FPM/FastCGI

It's webspace from a hoster... which line from the "phpinfo" do you need?

First I see it at the index.php but if I check other pages in the wiki (articles or special pages etc), I get the same error.
