Modules replaced by "Please contact support about"
Hello, I wonder if you could help me troubleshoot what happened to this tiki 6.2 installation: http://acpparma.net/Welcome
As you can see, several parts of the page (the menus and the banner modules) have stopped loading correctly: a mysterious broken string has taken their place ("Please contact support about").
The database connection is okay, because the rest of the site is functional (wiki pages, calendars, articles, etc.).
The problem stays even after logging in as administrator.
I am not the only one to have admin access, so I am not sure about what kind of action could have caused this. Any advice would be really appreciated!
