I've been hacked.
Both of my sites have been hacked actually.
The WP Username was changed (which i found out) and i can't delete it.
Over271 other ones i could delete on 1 website however.
What can i do, in general, because there's more than over a year work lost?
I doubt whether to choose for WordFence or SiteLock or Other?
I am not sure you need one of those pricey services. It's actually very easy to change or remove ANY use account for your website. Yes, it will involve directly accessing the database, but it's not hard at all.
I am not suggesting you do this, but I am sure you can find a reputable service for under $50 that can clean everything out for you.
