Because debug mode it turned off and CubeCart isn't coded to strict standards. Turn debug mode off and clear the log. Look out for exceptions only.

It's all explained on that page. It's a monthly subscription with minimum term of one month. Historically we charged the same cost as month one for an upgrade service. We haven't increased our prices in over ten years. If you sign up and want one month only please let us know.

We have an upgrade service if you need us to do this. I'm not sure what has gone wrong. Please do take a full backup always before attempting an upgrade.

Are all screen blank or just some? Check the php error log for exceptions and the CubeCart_system_error_log table in the database.

1.10.0 has been released which allows for API keys to be manually added. This allows you to bypass the onboarding process which currently has a fault. PayPal merchant services have told us that CubeCart is not the only partner currently facing this issue.

@little music maker did you get this resolved? I'll check with PayPal merchant services. Maybe you can both PM me your PayPal addresses so that I can ask them to check. Both maybe...

This means it's doing exactly what we want it to do. Removing potentially harmful data from bad bots. Hopefully it calms down as the bot gets bored.

Yes all official ones at the latest version should be fine. The PHP error log will give you more detailed information.

It's already compatible with PHP 8.2 and 8.3. Whether your 3rd party extensions or skins are is another matter...

USPS are soon to discontinue their old RateV4 shipping calculator. In response to this we have released a free new USPS extension to connect to the current API (3.0). We recommend that all our US merchants upgrade to this extension. More Information: https://www.cubecart.com/extensions/shipping-methods/united-states-postal-service-usps-api-3-0 Public forum discussion can be found here. To use this new extension, merchants will need to obtain a new Consumer Key and Consumer Secret.

Please send a support ticket with FTP access. Normally we require technical support access but we need to make sure PayPal is working.

Yes they should be able to help. They know the onboarding process for CubeCart as we work closely with them.

There should be a button to return to your store instead of that link to PayPal. I can follow up with PayPal on Monday if you wish.

There should be a blue button at the end of the process. "Return to CubeCart". You may have to scroll down to see it or hide a PayPal feedback going over it. Don't use the x in the top of the window to close it.
