Plugin does not work in in archive page

Thank you for reporting this.

Unfortunately I get a “You do not have permission” error when trying to view the screenshots. Could you upload them to imgur.com or another site?

sorry, it is :

Thank you for the screenshots.

Try this:
1. Remove all conditions but the first row
2. Re-add the conditions you want, but make sure to use the OR-separator, so that it e.g. says KB: Knowledge Base OR Categories

When using AND the conditions are evaluated as a group, meaning that your current conditions would only work for a single page that meets ALL the conditions.

This also makes the AND-separator very powerful: You could add a sidebar for kb articles only in specific categories or written by a specific author, etc.

Also, if you only want a sidebar to be displayed on archive pages, remember to click on “Settings” for the condition group and toggle the options Singulars and/or Archives.

Please let me know if you have questions about this!

Thanks very much，and for your detailed reply.

I try this setting: https://i.loli.net/2018/07/25/5b5829e0de876.png

but still does not work.

Is the default sidebar on the kb archive pages the Main Sidebar, or does those pages have a different sidebar, such as Archive Sidebar?

I will take a look at the plugin and see if I can reproduce the issue and get back to you asap.
