Whenever I update a specific file, the file doesn’t update, the file only updates if I change the subdomain. For example I have a css file with 1 line of code linked to a subdomain “FGX” and i change the css code to have 2 lines of unique code, “FGX” won’t update till lets say I change it to “fusion” then it changes, but if I change it back to “fgx” it will still have that one line of code.
It sounds like it could be a caching issue. You should check your cache rules to see if one is too aggressive and causing this.
