I have a big (maybe) problem.
1) After some months of inactivity (the last time I posted everything was ok), I tried to make a new post on my site http://www.polviscolo.it.
It was impossible; I did not see the "publish" button but only "send for approval" (or something like this, I use the italian version) even if I logged in as admin. After pushing the "send" button nothing happened, I was asked if I was sure and after confirming I have been sent back to a new blank article page; in the meantime the articles already posted work fine.
2) I tried to upgrade to 3.4.2 and it came out with an error, the site crashed and I had to restore from backup;
3) I tried to deactivate the plugins and nothing happened: after each trial it said that the plugin (any of them) had been deactivated but in fact it was not true, the plugins continued working as before.
Can anybody help, please? Any help will be greatly appreciated!!!
