I have been using custom fields for folders to organize my work for quite a while.
Currently, I lost the ability to create new folders with custom fields or edit custom fields for my existing folders.
I can reproduce this. A custom field does not appear on the folder-form despite being defined properly as a custom field under the Settings tab.
But according to @Ealfardan’s screen shot, a previously defined custom field is still present and functional. Is that correct, @Ealfardan, or have you taken screen shots from different versions?
Regardless, I am moving this topic to bugs. I also edited the subject to match my understanding of the problem.
Thank you, @Ealfardan. Because of the bug, I could not test that, since I had no folders with custom fields already existing. I wanted to be sure you were not showing the screen shot of your folder to illustrate what was supposed to be there, but was missing.
