What is the issue you’re encountering
I can’t upload media via Wordpress, cloudflare issue
What steps have you taken to resolve the issue?
I cannot upload images via wordpress and it’s a cloudflare issue.
I have multiple installs of wordpress on different sub domains, and the issue occurs on all subdomains, so it’s not an install problem.
it’s not a limits issue as the file limits were increased for 128gb to 512mb, and the files are much smaller.
I spoke to my hosting provider and this is what they reported:
This issue appears to be caused by both the mixture of Wordpress’s “Multi-file” uploader and Cloudflare proxying.
When attempting to upload a file to the media library using the “browser uploader”, found by clicking “browser uploader” at the bottom of the “Upload New Media” page in the WordPress backend, I am successfully able to upload an image.
When attempting to upload an image without Cloudflare’s proxy in the middle, using WordPress’ “multi-file uploader” I am also successfully able to upload an image.
However, when using both the multi-file uploader with Cloudflare proxying I encounter the error you have mentioned.
This indicates that the security functionality of Cloudflare’s proxy is interfering with WordPress’s “multi-file uploader”.
In this case, simply using the browser uploader in WordPress, or disabling Cloudflare proxying would resolve this issue.
I don’t want to be using the browser upload as this is too limiting and inconvenient.
