No, not always. It should clear the cache on the server but the browser will usually need clearing as well. While one could clear their own browser cache, that doesn't mean that the cache for other users will be cleared. Renaming the skin will force all browsers to download the skin again because they will see it as a new set of files. That's why the Skin Version Guid is so nice, we can effectively change the url the css without needing to rename the actual skin directory.

Hi,

I didn't say to change it to another skin and then back to the initial. I said to copy the current skin to a new directory and set the site to use the new copy. For instance, if the skin name is mycoolskin, copy it to a new directory named mycoolskin_v2 and then set the site (in site settings) to use mycoolskin_v2.

If the site is running 2.3.7.5 or newer, the "Reset Skin Version Guid" button is available and that can be used to avoid needing to copy the skin.

HTH,
