UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support Help Needed as Can't See Anything

After trying to set a directory for backing up tables and clicking on the test link, I can't see or access anything to do with UBB Threads.

I had changed some permissions when setting up the backups directory, which I deleted in hopes that all would work well again.

MySql database is all showing OK.

I have the forums directory set at 777.

Any help or advice would be appreciated.

Forum link is http://www.maritime-sda-online.com/forums/ubbthreads.php?ubb=cfrm

Thank you.

When I had set up and tested that directory, I had set it up as maritime-sda-online.com/forums/backups

Was that the web root directory that I should have avoided and is causing the problem?

I am using 7.4p2

This is what I get when I check out the page source:

How do I fix this?

I found this, but am actually afraid to use it.

What do you think?

My host provider ran a script and resolved the issue for me.
