hi all, I have an issue with my site that should be addressed fast! earlier today, I have noticed that someone logged into my Admin account, how? my forum's homepage changed to an error "Error code: EX0 ", then I went and looked on the administrator's logs and noticed someone installed through my account an application, then I immediately changed my password and uninstalled the application he installed, the error didn't go away, I started reading online and noticed some people said they had it with different applications. For example, someone installed the portal application and then this error came up, after reinstalling it, it fixed it for him. So I realized it has something to do with my forums app, i uninstalled it and installed again, I read carefully, I was afraid it'll delete some data so I figured, if it suppose to delete the stored data information I have it would simply tell me right? so i uninstalled it, installed again and noticed my entire forum is gone! no posts, no topics! only a single post saying welcome (automated one). How can I fix it? what am I supposed to do...? my mind is literally blown away right now. My forums has over 5k users in it and many old posts, would be unfortunate to lose it all because someone tried to hack my site. *THE ERROR is gone after reinstalling but like I said above, all posts, topics just disappeared,.... Any help will be appreciated. Thank you.
