Summary0027920: Mysql database compatibility

My question is the following I have MantisBt 2.24.4 and a MySql database in version 5.5.62, I have already made the connection, the Mantis has updated the database and I see all the data without any error, the question is that in Very often when wanting to do an operation on the mantis, he thinks about the page and ends up saying APPLICATION ERROR # 400.

TagsNo tags attached.

Error 400 is: Database connection failed. Error received from database was #%1$d: %2$s.
So I would expect that there is some more information in the error message that might help to find the root cause.

Check also your database server logs for errors.

This is not a bug or feature request for MantisBT (you are asking for help on how to deal with problems to connect to your database). I am therefore resolving this issue as "no change required".

Please use the forums to get support on customizing and using MantisBT (refer to for links and further details).
