please update to Version: 4.5.7. Regards.
can you tell me how can you do it safely with 1-Click Direct Upgrade module?MigrationPro Ultimate is a good module, I tested it and it worked perfectly without any problems, but I switched from the older version to presta 8 with the 1-Click Direct Upgrade module, because I needed to save the old tables with statistical data from another module, which I transferred perfectly to presta 8. This MigrationPro is suitable if who only want to transfer the basic presta tables and don't need old modules.
