Hi!
After migrating to J4, which in the first runs smoothly, I found, that the original masonry blog was shown in one collumn only. Checking the settings, I changed the linked category and saved. I should have done so! Because then, I faced first multiple errors:
1. The backend entry field for the categroy change its functionality (pic 1)
2. On the Front end a error was shown (pic 2)
3. I then tried to enter the category id (pic 4) in the backend which resulted in a different error message in the front end. (pic 3)
I did already reinstall the template (after deleting the HTML folder)
As an override, I also localized the fonts.
(BTW: Alternative and Masonry are showing the same behavior)
Thoughts on this?
