After updating from joomla 5.4.6 and jem 4.4.2 to to JEM 5.5.0 rc5 at 2026-07-02 1800 there could be an issue with the new map funtionality in venues.
If you create a new venue and don't copy the coordinates ( that means both coordinates are 0 ore empty) and you tick the include map, calling an event linked to that venue will cause and oops. After unticking -> no issues.
- Treat zero or partial GPS coordinates as empty coordinates to avoid invalid map output.
Next release: Only JEM 5.0.0 rc5 for Joomla 5 and 6 [03.07.2026 21:30]:
