I built a site for a client last year. They've been managing it day to day, and now they're seeing some strange behavior with menus.

Some menus are duplicated on pages.

And when I edit the module for a duplicated menu, the Menu Assignment list doesn't list the right pages. It lists two copies of a recently added page and the section name of the pages they were added in (About Us), rather than duplicated menu I'm trying to edit (Projects).

Any ideas? I'm suspecting a corrupt database, but before I do something drastic like completely re-install the site, I thought I'd ask for any pointers.

Has your client given you any information as to what they were doing when this happened? Has the Joomla! version on your client's hosting site been updated recently?

As far as I know, the client has only edited pages and added some pages. I wrote some basic directions for them. No upgrades to either the database or the Joomla version.

Do you have a URL for the site so we can take a look at what you mean?

thanks,
Jen

The client had a deadline, so we ended up installing an old Akeeba backup onto a new DB. So far, everything seems to be working.

If the problem appears again, though, I'll let you know. The strangest part wasn't what you could see in the public part of the site; it was the module manager listing two copies of a page as the only live pages on the site for placing a module. Very strange . . .
