Everytime I try to activate a theme, delete a theme/ post/ page, edit something, everytime I click on ANYTHING, try to change my password, log out, etc. I receive the following messages:
Warning: include_once(includes/custompost.php) [function.include-once]: failed to open stream: No such file or directory in /home/content/04/11479504/html/wp-content/themes/snaps/functions.php on line 215

I have contacted my web host and they were not able to fix this issue. I have no idea what it is or how to fix it. I have tried uninstalling and reinstalling wordpress several times. I have also tried clearing the cookies and cache and I am still having this issue. Sometimes I receive these warning messages when I try to log in to my account and therefore I can't even access my wordpress website.
