When the problems first started a few weeks ago I reverted to 4.4.1 via plugin edit (as you suggested) – and that resolved things at the time.
Then a few days ago I suddenly found my whole site down with 500 error and the slimstat-related msg posted by others.
I disabled slimstat (still at 4.4.1) via c-panel and deleted browscap-db.php.
Left slimstat deactivated to see what would be announced here (I can afford to be without it for a few days).
Now when I try to activate, update, anything, it gives me a 500 error (just in the plugins page, fortunately, not the whole site).
I note browscap-db.php has reappeared in my c-panel file manager – don’t know if that is good or bad?!
I’d like to get slim stat working again with my database intact if possible. Is there a way to recover this or should I delete and reinstall?
Thanks for your great free plugin and for trying so hard to help us all via this forum.
PS this may be dumb (I know nothing about all this stuff) but could it have anything to do with a jetpack conflict? I noticed when the problem first started and I was re-enabling plugins to see which had caused the problem – everything was fine till I had BOTH JP and SS active together. I deactivated JP and kept SS which seemed fine till this recent thing.
