So I made a massive update to my forums and all my icons and images are messed up and I posted this on the software’s forum and they said I need to do it host side / empty my cache. /var/cache is empty and I don’t see an option in the control panel.
There is currently no good way for it… As it is the client side cache instead of the server side cache.
You could consider to disable cache control temporally
add_header Cache-Control no-cache; expires 1s;
