Using php 7.1.7
Fix no. 2 worked, the beat version. Tried no. 3 first, but that didn’t do the trick.
Thank you so much!
The site looked fine until we updated to WP 4.8. Topics became cramped under forum and received an error message when trying to create a topic or reply to a topic at front end. Same error when trying to access forums at back end. Topics at back end show no topics.
Deleted the plugin, reinstalled and started fresh with a new theme. Still see the same old content and get the same error. This is the error message:
Fatal error: Uncaught Error: [] operator not supported for strings in /home/rsgtoday/public_html/forum/wp-content/plugins/bbpress/includes/forums/functions.php:1800 Stack trace: #0 /home/rsgtoday/public_html/forum/wp-includes/class-wp-hook.php(298): bbp_pre_get_posts_normalize_forum_visibility(Object(WP_Query)) #1 /home/rsgtoday/public_html/forum/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(”, Array) #2 /home/rsgtoday/public_html/forum/wp-includes/plugin.php(515): WP_Hook->do_action(Array) #3 /home/rsgtoday/public_html/forum/wp-includes/class-wp-query.php(1683): do_action_ref_array(‘pre_get_posts’, Array) #4 /home/rsgtoday/public_html/forum/wp-includes/class-wp-query.php(3248): WP_Query->get_posts() #5 /home/rsgtoday/public_html/forum/wp-includes/class-wp.php(617): WP_Query->query(Array) #6 /home/rsgtoday/public_html/forum/wp-includes/class-wp.php(735): WP->query_posts() #7 /home/rsgtoday/public_html/forum/wp-includes/functions.php(955): WP->main(Array) #8 /home/rsgtoday/public_html/forum/wp-admin/includes/ in /home/rsgtoday/public_html/forum/wp-content/plugins/bbpress/includes/forums/functions.php on line 1800
At this point, we would like to get rid of the content that is on the site now and rebuild the forum. The forum site is to be part of a multi-site network of three WordPress sites, so it is critical to get it working. Have read your documentation and will need the right sidebar on the forum.
