Hi there,
I am working on the time template and tried to change the background link of the demo imagevideo in the module Home Top A Video.
First everything was good, saving, refresh etc.
Than as I try to save the new changes of the Home Top A Video, it will download the index.php instead of saving, happens also with all other buttons, reminding me on the old php version issue.

It doublechecked:
Deaktivating the editor - no change
Try to save other articles, modules - all good
deleting cache etc. -. no change
Looking forward if anyone has an idea.
Many thanks and best
Dave
