Hi Diego,

Sounds like that's just the old module that was loaded. If you go to Admin > Site > Admin Console and then go to the middle of the screen, you should see a link for "Module Details", then scroll down and you'll be at a list of Unknown Modules where you can then delete the bad modules out of the LabKey database.

And yes, please refrain from using externalModules. Due to your instance of LabKey not being built from source, you will always want to build your modules within the modules directory instead or build them outside of that directory, zipping up the contents with a .module extension, then dropping that .module file into the modules directory.

Regards,

Jon
