Hi,
i installed joomla4, sppagebuilder and helix ultimate.
If I set helix as the default, site responses (img1.png) https://ibb.co/1JZRBJz: "sorry, there was a problem we could not recover form"
if i set cassiopea as the default, there isnt't problems and it works (img2.png) https://ibb.co/rHTd803.
more:
If I try to set helix, it gives me the following message (img3.png) https://ibb.co/zXtWfTX: "InvalidArgumentException: Please specify a valid response format, other than that of HTML, such as json, raw, debug, etc."
thanks for your help
