Experiencing the same behaviour here.
- with edge only.
- same warning on the console
SEC7113: Das CSS wurde aufgrund eines MIME-Typenkonflikts ignoriert.
- after choosing the new theme from the dropdown menu, there is a little lag an then comes a reload and all is broken. After a reload everything is fine again. If you manage to klick save before the reload takes effekt, you have your new theme.
We use the standard themes with hell, dark and light choosable and with DiscoTOC. Our Version is 2.4.0.beta10.
Our users cannot change their E-Mail addresses. They cannot choose their own locale. Username change period is set to 0. Users cannot set their own primary group. They cannot enable mailinglist mode.
This was reported by a User and we can reproduce the behaviour.
Since everything is okay upon reload, it is surely not urgent
