[Plugin: Developer's Custom Fields] Error on My Profile

Hey there, I’m seeing this error on the My Profile screen:

Warning: First parameter must either be an object or the name of an existing class in /Users/jonahwest/Sites/cococello/sites/the-photo-society/www/wp-content/plugins/developers-custom-fields/slt-cf-init.php on line 455

My profile info still saves but I get a blank page with the error when doing so.

Let me know if you need any more info.

Thanks,
Jonah
