First I got a warning that the connection was reinitialized, then when I tried to install the module again I got an error that there was already a menu entry with this name. While following this option:
[quote]Most probably some error with admin menu creation. Execute below query in database and reinstall component
delete from jos_menu where url like '%com_gpstools%';[/quote]
I decided to check what was written in the table. I found there was no component_id specified. I manually set it to the next available number, refreshed the cache and now all shows up.
