Well, that didn't take long. After releasing version 188.8.131.52 less that 48 hours ago, Prestashop have released version 184.108.40.206 to address the following issues:
Added Features: [+] MO : Shopping Flux / MailJet Fixed bugs: [-] BO : fixed bug #PSCFI-4154 - submit image product bug [-] SQL : fixed primary keys issue on Cart_product *
* The SQL fix listed above is very important in my opinion fix to prevent the following error: “You already have the maximum quantity available for this product.” when customers order multiple combinations of a product.
Looking for help or instructions on upgrading to Prestashop 220.127.116.11?
I recommend a read of the following threads on the Prestashop forum to help in upgrading any version of 1.4. i.e. version 18.104.22.168 to 22.214.171.124
