jOpenSim goes Joomla4

The current jOpenSim version under HEAVY development (v 0.3.1.5) already reaches many targets to be compatible with Joomla4.

With tonights nightly built (available at www.jopensim.com/jopensim3/nightly/ ) the admin pages should work mostly fine in Joomla4.

There are currently 2 known issues:

1. Admin pages with modal popups (like in groups or search) currently dont work yet ... fix is in progress
2. For frontend currently the file ./components/com_opensim/router.php needs to be removed (or renamed) to let links work proper
