No tags on my sidebar and I can’t change the order of categories.
About categories, I don’t think there is a setting for that. However, the sidebar follows
fixed_category_positions setting. You can achieve similar results, I believe.
About tags, You have the
default navigation menu tags setting.
If you want tags sorted, you have the
tags sort alphabetically setting.
default navigation menu tags, did you fill it with tags?
Now I see no tags can be displayed on my sidebar, at the same time no tags stored anywhere after I created tags.
I see the real problem is I can only create 2 words tags. If I try to create 1 word tags, no tags are really created. How can I create both 1 word and 2 words tags?
