Hi Jan,

My client's site which was referred to in the original post above sunkissedgirlz.com has been suspended by the host for exceeding CPU usage. In trying to track down the problem I have been uninstalling components and other Add-ons that may be causing the problem and have checked out the Error Log and found the same message (PHP Fatal error: Call to undefined function: array_diff_key() in /home/vickme2/public_html/skg/components/com_sef/joomsef.php on line 616) in the logs

BUT... the site is no longer in /home/vickme2/public_html/skg/ - The site was moved to a new server over 2 months ago and should be found in public_html/... Can you shed some light on this?

Your help is greatly appreciated.

Sincerely,
Karen

Thank you Jan,
this seems to have been the problem... I thought I was running 5.2.x all along and thanks to your response I contacted my host and it resolved the issue for quite a number of items that involved SEF.

Hello,

I just installed and set up the paid version of JoomSef on a website and am getting the following error when attempting to use the "Mail To Friend" feature (Mail To Component).

Please let me know if there is a fix for this error... Fatal error: Call to undefined function: array_diff_key() in /home/server_name/public_html/site_folder/components/com_sef/joomsef.php on line 616

Please see the site at www.sunkissedgirlz.com

Thank you
