I have a development copy of each of our sites, and a live copy of each. I was able to import all of the shortcodes and fix errors and save them on the development site, but when I attempted to do this on the live site, when i click the save button I am getting a "Forbidden" notice.
The Live site has W3TC, MaxCDN, Cloudflare, Wordfence, and blogVault installed, but otherwise the sites are identical.
