Site hack, now Unable to add cookies, header already sent error message
My site was hacked. We restored to an earlier backup and now there's a "Unable to add cookies, header already sent." message when we try to enter the forum. I tried cleaning up the config.php file.
I tried re-uploading everything, but overwrote the config.php in the process. How many config files are there in 4.2.1? Just the one in the Includes? I was intending to try again to upload all the files, unless there's something better I should try.
