I am having the same issue as this issue but their solution isn't working.
Basically my categories and tags keep dissapearing. The most commonly used ones still show up in the next tag but even when they are selected they don't stay when I publish, edit or modify. Does anyone have any ideas how to get my categories and tags to come back.
I installed a new tags plug in and they stayed. Should I use a categories plugin?
I get to this step where they have this url...mine is a bit different and posted below.
Here is the one from the example:
Here is mine...it points to tags instead for some reason:
Any help would be great. Thanks.
