I have no idea what is happening. I don't even know what information would be relevant, so please ask me anything you think could be related. The problem: I write a html script and css to modify it. I put the files on my webserver (Apache2 running on Ubuntu 22.04) and they work perfectly. I can modify the css script (e.g. changing font sizes, margins etc.) and the changes show up on the corresponding html. Yet, if I leave the laptop alone for an hour or so (not changing a thing), and I modify the css script it has zero effect on the corresponding html. It's as if no changes have been made. I can delete the files, write them over again and they work fine; leave it alone for a period of time and it no longer works. This holds true for all my html/css files. All help is greatly appreciated. Thanks.

I tried restarting Apache, restarting the laptop, rewriting the files, renaming the files, moving the files. No matter what I do, after a period I can no longer modify the html with css.

Deleting the browser cache seems to have worked. Such a simple solution. Thank you so much.

The first step would be to identify the source of the issue. This can be done by checking the Apache server error logs, as well as any other relevant logs from the Ubuntu OS. The error logs may help identify the root cause of the problem, such as a configuration issue or a software bug.

Once the source of the issue is identified, the next step is to attempt to troubleshoot the problem. This could include checking the web server's configuration, ensuring the correct permissions are set for the HTML and CSS files, and ensuring the server has the correct modules installed to support HTML and CSS.

Additionally, it may be helpful to check the browser's cache to ensure the HTML and CSS files are being served correctly, as a cached version of the page may be loading instead of the updated version.

Finally, it could be helpful to test the same setup with a different web server, such as Nginx, to determine if the issue is with the server or something else.

Ultimately, the devil in the details may be something as simple as a configuration issue or a software bug, or it may be something more complex such as an issue with the browser's cache. Identifying the root cause of the issue will be key to resolving the problem.
