Hi guys, something's very weird happening with my WP sites.. Both of them are on the same hosting, but different domains. Different themes, different plug-ins. Well, the only thing in common is the same hosting between them, nothing more. Here's the problem: today suddenly my sites stopped loading. I can log-in to admin panel, but the site homepage and none of the posts aren't showing. I checked my files and noticed that index.php file is blank (!) on both sites. I mean, WTF, how could they get blank? I did not edit them or something. Okay, so re-edited them and the sites started loading, BUT just about after few seconds my sites redirect to some CPA/PPI offers randomly. And the index.php files get blank again. After I re-edit the index.php sites, sites load, but again - redirect to some shitty offer and the file gets blank again.. I am thinking that my sites could have been hacked and someone is redirecting visitors of my sites to their offers.. But why in the hell the index.php files get blank by themselves? Anybody might have an idea what's happening and how could I resolve this issue?
