I have a problem when i choose the item category at the article creation process, the extra fields of that category are not showed, just a message in the extra fields tab asking me to select a category. It looks like the system does not notice that I've already selected the item's category.
Any help ? Thanks in advance for your time.

By the way, it just happens when i try to create a new item without selecting the category first. If i enter a category and then click the "New item" button, everything works fine.

Hello Diego,

Can you check the console tab of your developer tools for any JS issues?

It is solved! The problem was related to a weather module called POWr . I have unpublished It and now erything works fine.

Thank you for sharing the solution Diego :)
