Hello,
This specific error has been corrected but unfortunately more problems appeared with this update :
The sidebar (block options/menu) is not refreshing correctly
When I modify a block, clicking “Cancel” does nothing and i’m stuck with an empty menu
When clicking “Apply”, same thing, the menu stays empty and the changes are not applied. (Sometime also an alert appears : “Block rendering failed”)
I tried both with the Single Post block and my custom block, it’s doing that for both.
When I’m opening a block for the first time, the ajax response is a JSON, but with cancel/apply it’s plain text, not sure if this is intended ?
I’m available if you need me to do more tests
Thanks
