After 7.3 Upgrade Getting Fatal Error Message.

Not sure what happened but after 7.3 upgrade, I'm getting the follow error message anytime uploading images: 

Fatal error: Uncaught exception 'Intervention\Image\Exception\MissingDependencyException' with message 'PHP Fileinfo extension must be installed/enabled to use Intervention Image.' in /home/tops/public_html/plugins/intervention-image/Intervention/Image/ImageManager.php:123 Stack trace: #0 /home/tops/public_html/plugins/intervention-image/Intervention/Image/ImageManager.php(25): Intervention\Image\ImageManager->checkRequirements() #1 /home/tops/public_html/inc/classes/BxDolImageResize.php(44): Intervention\Image\ImageManager->__construct(Array) #2 /home/tops/public_html/inc/classes/BxDolImageResize.php(62): BxDolImageResize->__construct() #3 /home/tops/public_html/administration/basic_settings.php(310): BxDolImageResize::instance() #4 /home/tops/public_html/administration/basic_settings.php(30): setLogo(Array, Array) #5 {main} thrown in /home/tops/public_html/plugins/intervention-image/Intervention/Image/ImageManager.php on line 123

The site works fine other than this error.

I noticed a post from another user stating she had the same problem.  The answer to the issue was this:

This is the nature of the problem, fileinfo extension must be installed.  If it is installed, then you need to enable it.  This will depend on how your server is set up.  If you are running WHM/cPanel then you can do this through easy Apache.  If you are on a shared host, you will need to contact your hosting provider.

We did just move to another web host and are having them activate the 'fileinfo extension'.  If this takes care of the problem, I will follow up.

The above solution did not take care of the problem.  Does anyone have any idea what is causing this error message when uploading images?

What does your Admin Tools page tell you about fileinfo installed?

Our particular issue was resolved because it was an issue with our host server.  It was an issue with the 'fileinfo extension  So if you're getting the same error message (as above), that may be the first place you'll want to look

BTW, the 7.3 upgrade had nothing to do with this error.  We just happened to migrate our VPS to another host provider at the same time as doing the upgrade.  So it was a server settings issue.  Not a upgrade issue.
