I upgraded to Joomla 5.4.0 Stable yesterday and the all frontend pages are failing. Backend is alright and also is frontend editing through PageBuilder. Are some of the Overrides not correct? Difficult for me to tell.

Please advice. I have backup of both previous version and current. But I hesitate to roll back before you have a chance to see what has gone wrong.

Thanks // Jörgen
