Error loading logo

I just installed Dolphin 7.2 hosting with TMD hosting. Upon selecting a file to change the logo, from my local machine, I don't see anything happen. Then if I click upload I get the error below. I then upgraded to 7.3.1 and I thought that might help, but i get the same error. Can anyone advise me about this message? Thanks

Never mind to this. I got a reply from TMD hosting and they enabled to PHP Fileinfo extension, and now it is working.   Also, I realized that I should be posting to discussion group, not bug section unless I am certain it's a bug - will do that going forward. Sorry for this I am new to this forum and to dolphin.

Welcome to the forum.  It was important to install 7.3.1 as it contains the security updates.

If you look in your admin host tools it will let you know about missing things or permissions or settings that are set too low.
