I just went to upgrade to 1.2.5 from 1.2.4 & the package installer shows the upgrade as abantecart_upgrade_124. After clicking continue the following shows, which lead me to not agreeing. Is it just a typo both times?
Attention!
AbanteCart is about to be upgraded to version 1.2.4!
Automatic full backup will be created. It is recommended to try upgrade on test site first.
