As GM, every time I open edit character, while the character sheet has a tag added, the page becomes "Not Secure" (using Google Chrome), this seems to also extends file upload time, I think because it believes attackers can manipulate the images on the site but I don't know why. I have also found a work around: don't use tags. However, I want to use tags but can't figure out what else I can do (I did all of the previous steps available: GC on latest update but not beta, no extension interference, clear cache).
