Fatal error: Uncaught Error:  operator not supported – any clues?
I am using the bbPress forum at the moment for one way communication – later I expect it to become more interactive but for now it is more a record of the underlying story and issues. So I don’t check it often, last time was a month ago. Now it went to 404’s and page missing for everything. So I got the bright idea to run the Tool to repair it and selected everything. Now I only get errors for forums but the topics are working again.
See https://www.vrdriversim.com.au/forums/forum/technical/ for an example of the problem. Here is an excerpt, with myaddress inserted where my actual address was. Its a security thing for the long term.
Fatal error: Uncaught Error:  operator not supported for strings in /home/myaddress/public_html/wp-content/plugins/bbpress/includes/forums/functions.php:1800 Stack trace: #0 /home/myaddress/public_html/wp-includes/class-wp-hook.php(298): bbp_pre_get_posts_normalize_forum_visibility(Object(WP_Query)) #1 /home/myaddress/public_html/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(”, Array) #2
Yet in the WP admin panel I can see all the forums and they look fine. Here is an example of a working topic link: https://www.vrdriversim.com.au/forums/topic/green-screening/ which is a topic in the earlier given error example forum link.
I am also struggling to find exactly where the real files should be, so I can look there and see if they exist, or deal with restoring from back-ups, which I have, if necessary – once I understand what has gone wrong here in the first place! Could it be WP 4.8? I am on php 7.0.21, Apache server
I tried disable all other plugins, no apparent difference. I turned them all back on, still the same. Tried installing 2012 theme, no change (to forum link fails).
Over the last few days I have regularly deactivated and reactivated bbPress as part of working with the author of another plugin to find out why their admin panel is behaving weirdly (basically scripts not running without a page refresh or at all). So does deactivating bbPress break it at some level? Seems, from other posts here, it does for others, sometimes. Me too? How, or how fix is the more important q – stopping the behaviour comes later…
I posted this topic here: https://bbpress.org/forums/topic/vanished-forum-but-topics-remain-is-it-a-wp-4-8-issue/ but it isn’t listed in Troubleshooting and my profile says I haven’t started any topics. More weirdness. So 24hrs later I am trying again, few more details this time.
