How can I fix this?:mad:

You need to replace the missing file to start with also what vb version u using

4.2.2
What missing file?

this one that says it is missing check server error logs for more info

So?

You need to make sure that you upload the facebook.php file via FTP here: includes/facebook so the pathway would look like this: includes/facebook/facebook.php What that error is telling you is that the file itself is missing, it cannot find it where its supposed to be. So more and likely if you upload the file to the place its supposed to be you will not get that warning anymore.

The issue here is that his session storage path is not writeable. He needs to fix it, or his webhost does.

One of his problems not the only one

Per his error messages, that is the one and only issue here.

The missing file makes two as I said more than one problem
