I've searched the forum but either I'm missing it or just haven't found it yet, still looking but thought I'd go ahead and post it and maybe someone could send me the forum link or might be able to help.

Just installed EP v1.2.5.4 and it's showing under my tools menu but when I click on it I get this error message. Can anyone point me in the right direction for an answer?

"Fatal error: Call to undefined function tep_not_null() in /home/electric/public_html/admin/includes/classes/table_block.php on line 33"

Thanks
Jim
