An interesting issue, not specific to 2.4.2 but hilighted when I upgraded. I'm tired of having to create a new theme every time I upgrade, so this time I didn't bother. This resulted in errors for most users, as the selected theme no longer existed. Would be nice if instead of getting an error, the system just used the default theme. I changed the config for user preferences, so that they couldn't select a theme. I thought this would force it to use the default theme. but no, they still get the same error. perhaps the code could be changed so that it doesn't try to load a different theme if it's not allowed. should I enter these comments into bugzilla instead of emailing to the list? what's the usual practice here? Kind Regards, Andrew Glossop
