DbTableBase.php(395): Undefined Property: DetailPages

I’m using PHPMaker 2021.0.8, and after I have downloaded the latest extensions.zip, and installed/copied it to the extension folder (which solved another similar problem I had), it now caused a new problem.
I have the latest template (automatically downloaded) as well.So now when I go to the register page and register a new user through the registration page, I can still “Confirm”, but then I get the following problem:Error
C:\Apache24\htdocs\MyProject\src\DbTableBase.php(395): Undefined Property: DetailPages.I have used this page: Undefined Property and Obsolete Property to solve my previous similar problem.
I have the latest extension.zip file copied into the extensions folder.
I have he latest template.So it does not even write the new record/entry to the database.

Make sure you have already re-synchronized the latest database schema to your PHPMaker 2021 project, re-generate ALL the script files, and try again.

Thank you, did exactly that, however that still did not solve the issue.Here is the kicker. With Debug mode off, it seems to work fine, however with Debug mode on, it gives the above error.

You may enable Debug and enable Log error to file, run your script again, check the error log file and trace what triggered the error (i.e. which line of code used DetailPages). You may post the related log.

(If you use any custom or third party extensions, disable them first.)
