This happened with the latest beta release.
A large number of category group review/moderation moderators were added (approximately 338) to a group, which was then assigned to moderate certain categories. With the addition of category mods to the about page, it more or less broke the page. It took several minutes to display the large number of new “staff.” For some users, it failed completely, hung the browser, and had to refresh multiple times to get it to load. Volunteer with experience with Discourse also noted “Although here’s a bit of oddness, the JSON version for API usage loads almost instantly.”
Ultimately had to remove the group as a category mod, removing them from the about page, to get it to load again.
To explain the huge number of moderators: For our use case, we have a large number of local regions. These regions are headed by local volunteers, who by and large were responsible for modding their own regional forum. We have around 900 or so regional representatives who need to be able to moderate their local forum. This is especially critical for non-English-speaking regions.
We’re exploring other options to resolve this for now. Just reporting the issue with the about page!
