    Hi team, hope you're all safe out there..., This is a follow-on from: https://wplms.io/support/forums/topic/restricting-access-to-pages-based-on-course-category/ @Alex, we created a page template 2 years ago that restricts access to pages (based on the template) to certain types of logged-in users only (in this case students with a certain location taxonomy ID). Those pages are now showing a warning at the top of the page (but page still loads OK otherwise): Warning: count(): Parameter must be an array or an object that implements Countable in /home/customer/www/x.com/public_html/wp-content/themes/xchild/pagetemplatefromalexthatrestrictsaccess.php on line 40 Line 40 in that file is this from your original code: if(function_exists('bp_course_get_total_course_count_for_user') && count(bp_course_get_total_course_count_for_user(get_current_user_id())) > 0 ){ Any idea why this would now throw an error message after working for years? thanks On 3.9.9 now - old style

    if(function_exists(‘bp_course_get_total_course_count_for_user’) && count(bp_course_get_total_course_count_for_user(get_current_user_id())) > 0 ){
    change the above to : 
    
if(function_exists(‘bp_course_get_total_course_count_for_user’) && is_user_logged_in() && bp_course_get_total_course_count_for_user(get_current_user_id()) && count(bp_course_get_total_course_count_for_user(get_current_user_id())) > 0 ){

    Hi, Thanks but that gives the same error Warning: count(): Parameter must be an array or an object that implements Countable in xxx line 41 ps. I corrected ‘ for ' as it pasted incorrectly.

    corrected again we dont need count there : updated code : 
    if(function_exists(‘bp_course_get_total_course_count_for_user’) && is_user_logged_in() && bp_course_get_total_course_count_for_user(get_current_user_id()) && bp_course_get_total_course_count_for_user(get_current_user_id()) > 0 ){

    That seems to work. Excellent support - you're a star. I'll apply this to the other 'restrictive page templates' too (they have a different, shorter line 41 but seem to work with your new one too. The old one (where just removing 'count' does not work) is: if(function_exists('bp_course_get_total_course_count_for_user') && count(bp_course_get_total_course_count_for_user(get_current_user_id())) > 0 ){ I assume replacing it with your new one does not have undesirable side effects. Many thanks.

    No the new one is infact the correct code .Old one was wrong the function bp_course_get_total_course_count_for_user does not return array it returns integer and this is why the error was appearing .
