5 WordPress sites (that is all of them) on our server (Apache, Ubuntu) were infected by some malicious code injecting javascript. I have deleted all the wp databases that were full of the injections and reuploaded them back from a backup. Almost all is well now, but one of the WordPress sites from one domain now redirects automatically to another WordPress on a different domain, which shouldn't be happening. Both domains and WordPress installations are hosted on the same server and worked just fine before. The database seems to be ok, .htaccess seems to be unchanged, I certainly haven't changed any domain configuration files on the server, plus I checked them and they seem unchanged as well. I have no idea where the problem is. Could you, please, point me to a probable cause? I have very limited experience with sorting out this kind of troubles. Thank you.
