Sorry for the newbie question, but I just can't figure this out. I have tried to flush the Silverstripe cache using ?flush=1 on the blog summary page, and I've used it on the blogentry page. My changes to both templates are refreshed, but the css file is not refreshing. The file is uploading properly (checked by downloading to new directory on my laptop from ftp ), but when i grab the stylesheet using firebug, it's not the newest version of the stylesheet. I am assuming it's the silverstripe cache because it just sort of stopped updating during a string of changes.
Any help would be greatly appreciated!
