Issue: js/vendor/hammer/hammer.min.js.map does not exist

This may be related to this report.

It looks like something is happening when you try to upload an animated GIF when your PHP is compiled with Imagick support. However, the stack trace you posted above is missing the corresponding error message, so I can't be sure what its complaint is.

Here's everything in the error log.

That error message does not correspond to the stack trace. If this is truly what's in your log, you may need to restart your PHP process manager, because there are problems in your server's opcode cache.

Restarted both PHP and Apache, and it still has the same error.

Removed Imagick from PHP version website is using and it works now.
