It is possible that I messed with one of the core files (especially because I don’t exactly know what that means).
It is not a new blog; I’ve had it for about a year and a half. How can I back everything up and reinstall WordPress?
Here’s something else I noticed that seems off. When I switch to the default theme and go to a post that already has a comment written on it, instead of the comment, this error shows up on the site:
Warning: call_user_func(mytheme_comment) [function.call-user-func]: First argument is expected to be a valid callback in /home/content/33/5908533/html/wp-includes/comment-template.php on line 1334
Does this help? This is not an issue with the Snowblind theme, just the default.
Any suggestions on how to fix that then?
