How can I fix this problem

This problem is happening when I try to post a file. How can I fix it?


Looks like an issue with ImageMagick. Assuming ImageMagick is available on your server, you might want to check the path, which is currently set to /usr/bin/convert. Maybe try just /usr/bin.

I found out that my server had disabled ImageMagick, so I was experiencing this error. I changed the server and it is now working normally. Thanks
