This morning I tried to do some editing and the Art Library tab no longer loads. It appears that somebody changed the content asset requests to come from the other domain (non-dev) ? The console in Chrome Version 67.0.3396.87 (Official Build) (64-bit) shows several of the following: Failed to load <a href="https://app.roll20.net/image_library/validatefold" rel="nofollow">https://app.roll20.net/image_library/validatefold</a>... Redirect from '<a href="https://app.roll20.net/image_library/validatefolderstructure/" rel="nofollow">https://app.roll20.net/image_library/validatefolderstructure/</a>' to '<a href="https://app.roll20.net/sessions/new" rel="nofollow">https://app.roll20.net/sessions/new</a>' has been blocked by CORS policy: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin '<a href="https://app.roll20dev.net" rel="nofollow">https://app.roll20dev.net</a>' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
