Sometimes, i only need to switch categories 2 or 3 times to get that:

I tried several things, like disabling all the TCs and all the plugins, but the problem persists.

The only thing that works is [mydomain.com/?safe\_mode=no\_themes](http://mydomain.com/?safe_mode=no_themes)

I’m using the [FKB Pro - Social theme](https://meta.discourse.org/t/fkb-pro-social-theme/234323) now, i have already tested with other themes, but it’s always the same issue. What else can I try?

I’m using a ARM64 VPS in cloudflare.

Thank you

This is potentially going to cause an issue btw, e.g.:

I’m not sure how often that component gets redrawn, but the Ajax requests are not cached which may lead to unnecessary burden on the server, especially give how little that data changes over time.

Thank you very much. Hope there’s no problem with @Don theme. I will continue to investigate where’s the issue

i have made some others tests, and it’s looks like it’s related to the [Right Sidebar Blocks](https://meta.discourse.org/t/right-sidebar-blocks/231067) (or the fact that i’m using it together with the fkb panel, who comes with the [FKB Pro - Social theme](https://meta.discourse.org/t/fkb-pro-social-theme/234323). Its works fine without errors when i disable this tc, then visits the site in [safe mode](https://meta.discourse.org/t/using-safe-mode-to-troubleshoot-issues-with-themes-and-plugins/53504).

i dont know what to do now.

Maybe it’s not well configured?

for my blocks, i’m using `minimal-gamification-leaderboard` with no params. Same for `top topics`. Then i have `recent-replies` with count 5.
