This is basically just the Report tabbed menu on top. Under report, all that showed up was "Dashboard". This seems to be supported by the community version, since it was there when I installed it, plus it also shows up in the Community version online demo.

All I want to do is add more menu options other than "Dashboard". Maybe that's what caused the issue. Please let me know if there is a way to get it back, and thanks for all the quick responses.

Glat to see that you are back on track. Creating a new module can be a bit complicated. As much as we like to keep things simple, we have no choice but to introduce some complexities in order to support the kind of security expected in a CRM. The upshot is that you need records in the MODULES table and records in the ACL_ROLES table in order for a module to become visible. When you have all the SplendidCRM SQL source code, managing this is not hard, but when you don't, then it can be difficult.
