My site was not loading earlier, as I received a parse error referencing the general-template file located inside wp-includes. After replacing the file with a local copy, the issue was resolved.
I opened the general template file that had the problem and compared it to my local version. The bad file had this code inserted in it which prevented the site from loading:
<?php
//LINKBLOCK
//LINKBLOCK
?>
Does this mean my site was hacked? If so, would simply replacing this file fix the issue from happening again? I was running the latest version of WP, changed my pws, and looked through my files via FTP and didn't notice anything else that was strange.
