Actually it's with recent files at github..
I was able to reproduce this on JEM 5.0.1 RC4 / Joomla 6.1.2.
I tested the calendar views with an Event whose category has no color configured.
Result
The warning is reproducible in these three templates:
Code:
components/com_jem/views/venue/tmpl/calendar.php
line 451
components/com_jem/views/venue/tmpl/responsive/calendar.php
line 450
components/com_jem/views/weekcal/tmpl/default.php
line 408
The error is:
Code:
Warning: Undefined variable $color
The cause appears to be that
is only assigned when category colors are present, but later it can still be appended for Events whose category has no color.
The equivalent working templates already initialize it like this:
Code:
$colorpic = '';
$color = '';
So the minimal fix seems to be adding:
to the per-Event initialization in those three affected templates.
For comparison, these views passed with the same uncolored-category Event:
Code:
Calendar - Legacy
Calendar - Responsive
Week Calendar - Responsive
So this looks like a small JEM core issue rather than a configuration problem.
I also have a Playwright regression test for all six calendar variants, so after the fix I can rerun it and confirm whether all 6/6 pass.
