Sometimes you’ll see that your corrections to CSS or scripts don’t seem to work. If it is not an issue with your code, perhaps the problem is cashing either on the server or in the browser.
To me the best cure of caching issues is:
- Use a plugin to clear the WordPress cache
- The problem can be the browser cache, cure: Use a browser window that is not cached – e.g. a Fire Window in the DuckDuckGo browser, a private window in Chrome or Firefox.
- Sometimes you have to use yet another private / fire window in order to see the changes!
Here is a good article about cache issues when you develop WordPress.
