I am having trouble with newly created category. I don’t know if the problem came from the large image I set as a background or the name of the category (I used a french accent Matériel in the name).
Now, the page of the category just keeps loading indefinitely. I can’t change the name of delete the category so I can create another one.
I am going to answer myself (if this can help anyone in the future). The problem was indeed the weird accented name I gave to my category. The category just wont show so I can edit the name.
What I finally did is to update the category using the API as follow:
I created an API key in the administration page for my self (admin user)
went to the API endpoint for my forum and executed a curl put to update the category name (see here API endpoing
