I'm aware that this question has been posed before, so clearly it is an ongoing issue. I have removed W3TC according to the procedures suggested here (http://journalxtra.com/websiteadvice/wordpress/uninstall-w3-total-cache-proper-3920/), but it appears that the website continues to be cached.
It was through trying to update my site's primary stylesheet that this was becoming apparent. The changes are not being reflected even though the stylesheet has indeed been updated and saved correctly through FTP. The same holds true of my theme files.
I'm grasping at straws right now and would appreciate any advice.
My site is http://www.safeinternational.biz and is a multi-site installation.
