I am considering upgrading to S2MemberPro, but before I do, I want to know that the free version is robust and works well (since it’s the foundation of the Pro version) before buying Pro, so I’m wondering if you can tell me where I could find help with this issue (I can’t find anything in the free Knowledge Base or Forum):
I get an error message at the top of a page (Login Welcom Page) where I have several access restrictions. This is the error message:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘current_user_can' was given in /home/content/70/8904870/html/ultimateweightlossprotocol/wp-content/plugins/s2member/includes/classes/sc-if-conds-in.inc.php on line 138
I removed each of the access restrictions one by one (a "Get" short code, a customer capability short code, and a membership level page restriction) to determine which one was generating the error, and the error was still generated on the page each time I refreshed it after removing first the "Get" short code, then the custom capability short code, then the membership level page restriction.
