Closing the related GitHub issue, but here it is for reference: [Compatibility with CM Tooltip Glossary Plugin · Issue #546 · pressbooks/pressbooks · GitHub](https://github.com/pressbooks/pressbooks/issues/546) Basically, @SteelWagstaff was running into issues where non-admin users were getting “Unsupported post type” errors and permalinks weren’t being properly refreshed. Is that an accurate summary, Steele? Will post a few related items below. ---

Was anything resolved with the CM Tooltip problem? I am facing the same issue myself. ---

Hi, @gabriel.higginbotham—I’ve discussed the specific barrier to getting this plugin functioning with @SteelWagstaff (it was the post type restrictions, right Steel)? Specifically, Pressbooks currently only allows users to create specific post types: see [here](https://github.com/pressbooks/pressbooks/blob/dev/includes/admin/pb-laf.php#L633) and [here](https://github.com/pressbooks/pressbooks/blob/dev/includes/pb-posttype.php#L13-L23). If one were to add a filter to that array of post types, the CM Tooltip Glossary plugin’s post types could be whitelisted. ---

@ned Thank you! Would adding the post type (‘glossary’) to the array have undesired effects? I am not completely proficient in PHP, so I am not entirely sure what you mean by ‘filter’ in this case. ---

It would, but we don’t want to add every possible post type that users might want to support via third-party plugins to our core list of post types. What I mean by filter is this: [https://developer.wordpress.org/plugins/hooks/filters/](https://developer.wordpress.org/plugins/hooks/filters/) If you could test just adding the post type to the array and confirm that it works, I will go ahead and add the filter. ---

Hi @ned and @gabriel.higginbotham, I just added ‘glossary’ to the array in pb-posttytpes.php and it resolved the issues we were having earlier. Looks like a very simple fix, so thanks for helping, Ned! If you create that filter, we can probably create a sample functionality plugin in short order. Would you like help with a pull request? ---

I would greatly appreciate a PR! Please create a feature branch from dev (named something like `filter-posttypes`) in your fork, and use a filter name like: `pb_supported_post_types` when filtering the array in [https://github.com/pressbooks/pressbooks/blob/dev/includes/pb-posttype.php#L13-L23](https://github.com/pressbooks/pressbooks/blob/dev/includes/pb-posttype.php#L13-L23). ---

If you want to reference [https://github.com/pressbooks/pressbooks/issues/546](https://github.com/pressbooks/pressbooks/issues/546) in the PR that would be great too! ---

Following up on this. Ned added a custom post types filter to 4.0 (released earlier this week): [https://github.com/pressbooks/pressbooks/blob/4.0.0/inc/posttype/namespace.php#L16-L29](https://github.com/pressbooks/pressbooks/blob/4.0.0/inc/posttype/namespace.php#L16-L29). If you want to add ‘glossary’ to the array of permitted post types, one way to do it would be to add this code to a functionality plugin: \ ---
