Hello,

First of all, I want to say that I have checked all the related problems but they were totally useless for my situation.

This problem occurs when I try to log in, register, post a question and a comment.

There was a virus in my html files, including q2a files. The virus was adding a code to the top of the html files. Thanks to a application, I managed to delete all the malware codes. But after I deleted them, this problem has started to occur.

In my error_log these problems occur:

 PHP Warning:  session_start(): Cannot send session cookie - headers already sent by (output started at /*********/index.php:2) in /*******/qa-include/qa-app-users.php on line 149
 PHP Warning:  session_start(): Cannot send session cache limiter - headers already sent (output started at /********index.php:2) in *******/qa-include/qa-app-users.php on line 149

Hi,

It seems that while cleaning your infected files, it has either removed required code or there should be few files which are still infected. If I were you, I download the files and plugins from website and reupload them. This will make sure that we don't have any infected files on the website.
