I try activating the plugin and it causes an error on wordpress, I have to manually remove the plugin to get wordpress to fire up again...
PHP Warning: is_readable(): open_basedir restriction in effect. File(C:\[sitefolder]/wp-content/plugins/C:\[sitefolder]\wp-content\plugins\facebook/languages/facebook-en_US.mo) is not within the allowed path(s): (C:\[sitefolder]\;C:\Windows\Temp\) in C:\[sitefolder]\wp-includes\l10n.php on line 339
I noticed that there are quite a few other sites with the issue if you google it.
The file facebook-en_US.mo doesn't exist in that folder or anywhere in the plugin folder at all. I tried creating a blank text document of that name on the server and that didn't help.
This is a windows server running on plesk.
Any ideas on how to solve this? Thanks!
