Cannot upload image

[JoramD]

I cannot upload certain images to my gallery (the image attached for example).

I don't get any error just a very weird page, nothing in the admin CP either. Converting it to a .jpg seems to work but this obviously isn't intended behavior.

(Too much to paste as text)

Please contact your hosting provider, outputting the contests like this usually indicates that there is a configuration error on the server.

This is self-hosted, I have tried looking around but cannot find what the issue would be.

You will need to contact your hosting provider or hire a server administrator if you are unsure. This generally is a configuration error as mentioned and hosting services are outside our scope of support. I will move this to our self-hosted forum for assistance for you from fellow community administrators.

How many images do you try to upload together? This also happens to me when I try to upload many images all at once, especially if they have a "major" size.

This is precisely why I upload about 10 images at a time, not more.... Obviously depending on the size.

I had it happening with one and two 2.6mb .PNG files

This is either a server configuration with your PHP or you have a security tool like mod_security or a cloud WAF or something similar causing problems.
