Ok, please leave some URL to an example and send admin login details to supportgvectors.com to allow us find the problem and fix it. This is not a general issue nor wpForo bug. Something is damaged in your database so we only can fix it on your website.

I followed your steps and then tried to create my subject and I have this error that appeared:

SELECT `slug` FROM apedys_wpforo_forums WHERE `forumid` =(SELECT forumid FROM `apedys_wpforo_topics` WHERE `topicid` =(SELECT `topicid` FROM `apedys_wpforo_posts` WHERE postid = 38689))

Also please navigate to My Profile > Account page and make sure you have Display Name. Set display name and save it. Then navigate to Dashboard > Users > Your Profile and make sure you have a Display Name.

Please delete all caches in Dashboard > Forums > Dashboard admin page and try it again. Use other titles for topics, don't always use the Test word.

Thank you, with this solution I was able to delete my topic but I still have this problem when I recreate a topic and click on it to post a message nothing happens.... You can try it yourself on this link http://www.apedys.org/federation-anapedys-forum/scolarite__7/ : the test subject.

If you have a way to solve this, it will save my life!

You should delete it in database. use your Hosting Service cPanel > phpMyAdmin Database manager, navigate to WordPress Database, find wp_wpforo_topic and wp_wpforo_posts table and find the topic and post you're mentioning and delete.
