I've encountered a strange problem that I've never seen before. I edited a CSS file and uploaded it to my server. From my hosting's file manager, I can see the file is updated. But in my local computer, it is still the old version.
I cleared browser cache, I used another browser, I even switched to use my cellphone's browser, the CSS is still the old one. So I guess this is a server-side issue.
I logged-in to Joomla, and cleared all the cache I could find, but the file still won't update.
So where could this cache be stored?
Edit Through Developer's tool, I click and open the css file in a new tab, it is here that I see the CSS file is still the old version. I pressed F5 to refresh this file in browser tab, normally this will force the browser to check if there is a newer version, but the file still won't upgrade, so this is definitely something else. PS: I am pretty sure I didn't mistake the file.
