I have a simply web page based in wordpress in where I edit web pages with the wordpress visual editor. It is weeks since my last edit, yesterday I begin to edit a new page with visual editor but .... I get a blocked content image. If I change from "visual editor" to "code editor" I can use it, but I can not use the visual editor. In console I can see this message: Refused to frame 'blob:https://diydsolar.sytes.net/a2b69832-2d99-45dc-b760-766c6f933c04' because it violates the following Content Security Policy directive: "default-src *". Note that 'frame-src' was not explicitly set, so 'default-src' is used as a fallback. Note that '*' matches only URLs with network schemes ('http', 'https', 'ws', 'wss'), or URLs whose scheme matches `self`'s scheme. The scheme 'blob:' must be added explicitly I have tried by deactivating all my plugins (only a few and not changes since months) but no luck. I have tried also but there isn't any update for wordpress The server is a Google Cloud Free Tier. Any key to investigate? Thanks a lot.
