Ok I just read modernloopers list of questions so I want to make this as clear as possible. First this problem is not a plugin problem. I disabled and deleted all and it didn’t fix the problem. I also tried a different theme and it didn’t fix the problem so it is not a theme problem. TJ at Buddyboss tried valiantly to figure out the problem to no avail.
Here are the questions that modernlooper wanted answered.
Please try to supply answers to the following questions.
1. Which version of WordPress are you running? 3.81
2. Did you install WordPress as a directory or subdomain install? directory
3. If a directory install, is it in root or in a subdirectory? root
4. Did you upgrade from a previous version of WordPress? If so, from which version? every one for the last year
5. Was WordPress functioning properly before installing/upgrading BuddyPress (BP)? e.g. permalinks, creating a new post, commenting. Yes
6. Which version of BP are you running? 1.92
7. Did you upgraded from a previous version of BP? If so, from which version? Every one for the last year until 1.9 and then it broke. I just went back to my backup and waited. Upgraded to 1.92 and it is still broken. Went through all the normal troubleshooting processes until figuring out it was the notifications that is causing the error.
8. Do you have any plugins other than BuddyPress installed and activated? If so, which ones?
Ads Manager WP/BB
Akismet
BBpress
BB Force Profile
BuddyPress Tiny group chat
BuddyPress Links
