* Hi there, trying to add images to existing gallery. Was able to upload images
earlier today and now error ‘using runtime:html 5’ appears when I try to upload
any image. Could you advise please? Many thanks

* [@sara](https://wordpress.org/support/users/sara/) Bennett – If this was working
then stopped, it could be a caching (or security) plugin / service that is creating
this issue.
* Have you looked into that on your site and server?
