There are a very few hosting services with MySQL server configuration which doesn't allow wpForo to complete all tables installation on activation process. This is the main reason why you get "Topic Add Error" when you try to create a new topic:
If you got this error please follow to this instruction:
You should open hosting service > cPanel > phpMyAdmin database manager, navigate to SQL Ta:
Then insert the SQL mentioned below to the SQL query textarea. If your WordPress table prefix is not wp_ replace all wp_ prefixes in this code to your database table prefixes, if they are wp_ just use it as is:

After executing this SQL you'll get message "MySQL returned an empty result set...", this mean all is correct and already created:
This SQL query creates missing tables:
That's it, this is a one time manipulation, there will not be other issues in future.
Hello, I have inserted your code, except I replaced "wp_" to "_wp" ...new tables were created, but the error is still present, do you have any other solution?
You've created tables with incorrect table prefix. Wy you've changed "wp_" to "_wp"? I don't think your table prefix is "_wp". Could you please leave some screenshot of your WP tables?
Robert!
I executed the sentence at my db but the issue persists. Heres my db structure
Hi dalejandrom,
Please Uninstall wpForo (not deactivate), it'll remove all tables and data. Then Install it again. Then use the SQL above, I just updated and adapted for current wpForo versions. That was a little out of date. Now it should work fine.
