@dougevans. Thanks for posting. The information provided to you at the end of the module is not an error. It is some information about your php setup to see how compatible it is for detecting the MIME type of the file. So, first off, don’t worry about that.
For someone with PHP 5.2, it is typical to have FILEINFO_MIME_TYPE not defined and mime_content_type unavailable. I provide that information to make it easier for me to diagnose any problems and to give advice as to how to make everything work for your situation.
With that said, Doug, I can definitely help you. Send me either a screenshot or description of the error you are getting when you upload a file. The great thing about your situation is that exec is working on your host, so, we can move forward from there.
