Browser cache? Depending on your used browser, try hitting CTRL+SHIFT+R or CTRL+F5 or something similar to do a force reload of the page. Depending on your used server, your server might be able to serve ETags for files to indicate the last modified state. When you are in the testing phase you probably want to disable data caching in the player settings. However this does not necessarily disable all caching. Depending on your server configuration / behaviour your browser might still cache certain files. However forcing a cache clear reload should always fix caching issues.
