I have to remove themes and few addons due to security issue. Forum got infected with some malware for few hours yesterday as someone was able to inject something in few files. To get rid of that, I had to remove them and reinstall forum again. Site is back to normal now. Even though I was able to identify the issue almost instantly, I would advise you to check your system with your antivirus if you visited us around evening yesterday i.e may be between 6PM- 10 PM IST (+530 GMT). Sorry for any inconvenience guys.
