XF 1.4 Help!! Xenforo Errors

Been going on for a week now, my host and I have no clue how to fix it from happening on and off. But this is the error

An exception occurred: Cannot send headers; headers already sent in /home/enixor/public_html/forum/index.php, line 2 in /home/enixor/public_html/forum/library/Zend/Controller/Response/Abstract.php on line 321

Do this:

Admin Control Panel -> Tools -> File Heath Check
Thank you, what I did was I reuploaded the entire library folder, and that seemed to fix the issue for now. I did click on file check and all files were clear, no issues. I'll keep a look up to see if it keeps happening.
