Hi, I am also trying to upgrade on my local PC and can't seem to get the:
Hostname—hostname of your FTP server
Username—FTP username
Password—FTP password
Directory—the directory on the FTP server where CS-Cart is located
correct as it keeps asking to set permissions:
Permissions issue
These files require write permissions set (manually or automatically via FTP)
I am using Windows 10 and Xampp. The address is localhost and the folder is cpcomau (i.e. C:/xampp/htdocs/cpcomau/). The database uses root without a password.
I think all you need is to get your hosting to allow you to have a memory_limit setting of 256M temporarily for the upgrade. You could set it back afterward. However, most import/export type operations are performed in memory so if you use Google feeds or do other import/export operations you may find that 128M is simply not enough to operate cs-cart in all modes.
