Loss of session

For payment via PayPal to work correctly, it is necessary that your browser continues to send the identifier of the previously used session (session cookie) when you return to the shop after PayPal authorisation. This is apparently not currently the case if you receive a "session interrupted" or similar message. One possible reason could be the use of "antivirus" software or other "internet security" software. Please deactivate such influencing factors. You can then log back into the shop and continue shopping.
