Hello,
Looking your forum I found this article:
https://archive.joomshaper.com/forums/front-page-editor-cannot-save-changes
That is exactly the same issue than I’m having.
Under the “Accepted Answer” it says “problem was your xampp”..
I’m using MAMP (last free version), but I see that the person that reported the issue mention MAMP too, although packaged by Bitnami. I’m using this one https://www.mamp.info/en/mac/
I'am really lost at this point, I already did everything that the person mention in the forum, so I don’t know what else to do…
The localhost is under macOS Big Sur Version 11.6.
Thanks for your help!
