While working on a Django app within a VirtualBox VM running Ubuntu 14.04, I encountered an issue with CSS stylesheets. Despite making changes to the stylesheet, the Firefox Style Inspector still displayed the old version. I have tried various methods such as clearing the cache, using add-ons for cache clearing, and eliminating browser history. However, even after restarting Apache or the VM itself, the problem persists.
I suspect that there is a cached copy of the stylesheet causing this discrepancy but I have been unable to locate it. The situation is reminiscent of a similar issue with nginx discussed on Stack Overflow's website (nginx on VirtualBox Ubuntu guest serves stale content) although it did not offer a solution relevant to my case.
No errors are visible in any of the developer tools windows and the application functions correctly apart from this styling concern. If anyone has insights into resolving this dilemma, I would greatly appreciate your assistance.
