Hi there,
Thank you for bringing this issue to our attention. I apologize for the inconvenience you're experiencing when trying to make a purchase using PayPal with our JoomShaper EasyStore extension.
This error message typically indicates a problem with the PayPal integration. Here are a few steps you can take to troubleshoot the issue:
Check PayPal Configuration: Ensure that your PayPal credentials (API username, password, and signature) are correctly entered in the EasyStore settings.
Test Mode: If you are using PayPal's sandbox (test) mode, make sure that it is enabled properly. Conversely, if you are using the live mode, ensure that the sandbox mode is disabled.
SSL Certificate: Verify that your website has a valid SSL certificate installed, as PayPal requires a secure connection for transactions.
mod_security: Disable mod_security temporarily on your hosting server to see if it resolves the issue, as it can sometimes block PayPal’s responses.
Update Extensions: Make sure that your JoomShaper EasyStore extension and Joomla are up to date with the latest versions.
Server Logs: Check your server logs for any errors related to PayPal transactions.
If you continue to experience problems after these steps, please let us know. We are here to help and will work to resolve this issue as quickly as possible.
Thank you for your patience and cooperation.
Best regards,
Toufiqur Rahman (Team Lead, Support)
