We’ve noticed that since moving our website to slickstack, UTM parameters that have spaces converted to %20 break the page and returns a 410 Gone (Nginx error).

example > http://www.mywebsite.com/?utm_source=Referral%20website%20campaign
returns a nginx error.

however > http://www.mywebsite.com/?utm_source=Referral+website+campaign
works fine

So using + instead of %20 to interpret spaces in a UTM string works fine Is there a security parameter to change in nginx to allow %20? We don’t always have control over how online ad systems and referral websites will build the UTM and this glitch can essentially ruin an entire campaign.

Okay we patched this:

https://github.com/littlebizzy/slickstack/commit/6c985b10f304f0b30d8f37320c6f9b575f74085d

Please try now, it should not affect query strings anymore.

Amazing, so has that been pushed lived across all websites built with SS without needing any manual update? I wonder what unprompted API calls or updates are slickstack websites allow to perform in the background

You need to update to latest SlickStack build MAY2026G

So just login to your server via SSH and run ss update config and ss install to reinstall the entire stack again. Or ss install nginx config would also be enough.

Here is default crontab. You can remove the automated calls to Github if desired, to make your SlickStack server more isolated.

can LittleBizzy “takeover” my SlickStack server remotely?
