I'm getting a strange error when I try to add an image to a page. The site has been running for years, is on a theme based on Typhoon, the server is running fine, but when I add an image to a page the image get a big exclamation mark next to it. On mouseover I get what looks like the HTML to an error page.

The dev site works fine, and I added images to the public site last week with no problems... I'm a bit lost.

It has resolved itself. 30 mins of madness?

I'm getting the same error. The main message in the source code HTML that pops up is "Enable JavaScript and Cookies to continue".

On the GRAV logs I'm getting

 `/home/invitati/public_html/vendor/filp/whoops/src/Whoops/Run.php(514): Whoops\Run->handleError() 
 /home/invitati/public_html/system/src/Grav/Common/Errors/SystemFacade.php(43): Whoops\Run->handleShutdown() 
 [internal function]: Grav\Common\Errors\SystemFacade->handleShutdown() 
 {main}`

On the browser console I'm getting:
Experiment add-an-image-to-pdf-with-alt-text-rollout has unknown featureId: addAnImageInPDF RemoteSettingsExperimentLoader.sys.mjs:954:21

I have a dev site on a local server and everything is still running fine on there.

I have no idea what might be going on, all help appreciated.

@dan-james, In the first image you shared, it seems an entire page, titled "Just a moment", has been returned to Admin.

• I've searched the Grav+Admin code source, but it does not contain "Just a moment"
• If Grav were to handle an error, I would suspect another result.
• Maybe there is something between Admin and the Grav server in your production environment that returns a page?
  Cloudflare perhaps?
• When searching the web for Cloudflare "just a moment", there are quite a few hits about a so called "Just a moment Page"...
  • About it being an issue
  • And how to solve it

Cloudfare would be my first pick and I cannot help you with that...

Thanks - I'll try turning Cloudflare off and see if that solves it ... if it does, I'll investigate further.
