Request Entity Too Large – /wp-comments-post.php

Hello,

Got WP installed up and running. Added a comment plugin that allows for image uploads. EVERYTHING FUNCTIONING FINE! 3 Days later when trying to upload a picture with comments section I am getting this error:

Request Entity Too Large
/wp-comments-post.php
Does not allow request DATA with POST requests or the amount of data provided exceeds the capacity limit

Again, everything was working fine yesterday? So what changed, I guess the amount of data total that had been uploaded? Please help, I have no idea how to troubleshoot this.
