Weird PHP Error?

[edgeyveggie]

I'm getting this error all of a sudden when clicking "New Posts" or "What's New?" Any ideas how to fix this? The last thing I did was install an add on for adding signature restrictions, but I disabled the add on and it's still doing this.

Warning: require_once([path]/vb/search/core.php) [function.require-once]: failed to open stream: No such file or directory in [path]/search.php on line 87

Fatal error: require_once() [function.require]: Failed opening required '/home/site/public_html/site/forums/vb/search/core.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/site/public_html/site/forums/search.php on line 87

The error is pretty specific - it can't open the file - "No such file or directory". Do you have a file at /home/site/public_html/site/forums/vb/search/core.php ?

This is so confusing. No those files aren't there--I go into that directory and don't see either a "core.php" file or anything. This is really confusing because this was just working the other day and NOTHING was touched/changed, is there any other explanation for this?

You went into the correct directory and it's not there? Did you add it back? And then talk to your host about how it disappeared?

Just wanted to update this thread. I contacted my host and they said they had no idea how it disappeared but I simply replaced it and the problem SORT of went away. Now when I click "New Posts" it loads, but at the top of the screen over the content of the site I get this error:

Warning: call_user_func(vBDBSearch_Core::init) [function.call-user-func]: First argument is expected to be a valid callback in [path]/vb/search/core.php on line 86

Any ideas on this?
