Wiki Categories functionality + Hide Wiki history tab

Hello, there are 2 topics in this support ticket…

Topic 1 – WIKI CATEGORIES FUNCTIONALITY

The Wiki Category feature is not functioning correctly. I have designated categories for several different Wiki entries, and the category displays correctly at the bottom of the entry, however…. when that category is selected (either from the bottom of the entry OR from the category listed in the sidebar widget) it returns with a 404 error, page not found.

Additionally, for the Wiki entries that I have designated with multiple categories, there is no space nor comma separating one category from the other in the listing at the bottom of the entry.

Topic 2 – HIDE WIKI HISTORY TAB

Is there a way to hide the Wiki “history” tab? Our Wiki will be editable by admin only, and there is no reason for public users to be able to see revision history.

Thank you in advance for your help. This is my first experience with the Wiki plugin, and I am installing it on a site for a customer who is very familiar with Trac Wiki and would like to use something similar on his WordPress website.
