I just upgraded my ExpressionEngine to the latest version (2.8.1) along with the latest FieldPack (2.1.1). All my pages load fine, but when I try to click on an existing Custom Field within my ExpressionEngine Control Panel, I get the following error:
Unable to load requested field type file: ft.rel.php. Confirm the fieldtype file is located in the expressionengine/third_party/ directory
I read that PT doesn't support it anymore, but I'm not using any fields that use FT's old field type anyways, so I'm not sure what's going on. I basically can't edit any existing custom field without getting the error message. Any idea what's going on? Thanks!
