When I try to upload a new file in the downloads system, a page appears that says "Something went wrong. Please try again.".

The image I am including with the uploaded zip file is a standard JPEG.

System log reveals this error:

InvalidArgumentException:  (0)
#0 /home/xxxxxx/public_html/community/system/File/File.php(1578): IPS\_Image::create('????\x00\x10JFIF\x00\x01\x01\x01\x00...')

This behavior is new since I upgraded from IPB 4.2 to 4.7.20. I am thinking it is probably best to resolve any issues before moving forward with the upgrade to v5.

I also tried reverting to the default forum theme, but it made no difference.

All required information is included in the client area.

Are you happy for me to test an upload anywhere on your system? Just asking as Im fully aware you are heavily integrated with downloads

Yes, you may go ahead and try it. It won't hurt anything, but even if it does, all users with access to this feature understand they have opted into a beta and they expect bumps.

Please downgrade PHP to 8.1 as you're running an incompatible PHP version.

That fixed it, thank you.
