It' seems a bug but this is the story:
We created some organization category classes with neme cointaning accents character ((Ie. Biodiversità) and so we use them to categorize some portal items
One day We noticed that in the "content page" if we filter for those classes. no items is shown..
We tried so to rename the classes to eliminate the special chracter "à" but edit fails
We tried to delete the classes but the delete fails.
"Failed" means that Portal application remain in waiting status and no message is shown.
Notice that if I create a new class WITHOUT SPECIAL CHARACTERS I can edit or delete it without prioblems
Hany help is appreciated!!
