You can clear the cache in your site by adding /clearcache to the end of the url of your site. As an example, go to websitename.com/clearcache. The site will spin for a few seconds as the process completes. If the site is a B2B site, you will need to be logged into the site before you can access the /clearcache page. You can also try using this same process with /flushcache to see if that helps as well.
