Blank screen w/ error message
I browsed through your forum to find out if there was a solution to my problem but didn’t find any suitable answer.
My website for the forum-section is : http://cdf-lardy.fr/forums which results in a blank screen. In the back-office, i can simply create new forums but cannot access the “forums” or “All forums”-view, giving the same blank screen.
WP : 4.7.4
bbPress : 2.5.2
PHP version is 7.1
All other plugins are updated, i tried to disable them all, no changes.
I enabled debug function and got following message :
Fatal error: Uncaught Error:  operator not supported for strings in /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-content/plugins/bbpress/includes/forums/functions.php:1800 Stack trace: #0 /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-includes/class-wp-hook.php(298): bbp_pre_get_posts_normalize_forum_visibility(Object(WP_Query)) #1 /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(”, Array) #2 /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-includes/plugin.php(515): WP_Hook->do_action(Array) #3 /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-includes/class-wp-query.php(1681): do_action_ref_array(‘pre_get_posts’, Array) #4 /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-includes/class-wp-query.php(3238): WP_Query->get_posts() #5 /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-includes/class-wp.php(617): WP_Query->query(Array) #6 /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-includes/class-wp.php(735): WP->query_posts() #7 /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-includes/functions.php(955): WP->mai in /customers/4/9/2/cdf-lardy.fr/httpd.www/wp-content/plugins/bbpress/includes/forums/functions.php on line 1800
Does anyone have a clue ?
Many thanks in advance
