Product Customization Image Upload Giving Error "Format Not Recognized" w/ Valid imgs PHP7 PS1615

[protechtrader]

I can not get a image to upload via the default Product Customization file field.  I have tried to troubleshoot this in all the ways I could think (listed below) but I have not made any progress.  The error stays unchanged through all of the things I have tried.  Any suggestions are appreciated!

 

Error Displayed on Front End: "Image format not recognized, allowed formats are: .gif, .jpg, .png"

 

Apache Logs and PHP logs show no errors with and without debug enabled

No new information with debug enabled

 

Things I have tested that have not had any effect:

Disabled all Prestashop caching and CCC, and cleared cache through back office and manually

CHMOD 777 Full PS for testing

CHOWN All PS to www-data

Increased PHP file upload and PS customization upload limits

Replaced imagemanager.php class with original from github

Tried new DEV imagemanager.php class from github

Attempted multiple img types (jpg, png)

Attempted with multiple fresh images, and even blank jpg saved from ms paint

Verified drive space is available

Reloaded apache

Tried on multiple products with product customization file field

Verified normal image upload for a product main images still functions fine with same files
