I have read through the other postings on this very matter but cannot find a solution. I remove my api credentials since I’ve been using the same ones since 2013. I copied and pasted the new password and signature but when I tested the connection, I received the error message
Security header is not valid
Now, I remember this very same fight in 2013 and every time before that. I remember it taking days of fighting with the program to get it to work. The information is all correct, yet I continue to receive this error message. I knew I should not have changed this info but I thought it was time for an update.
We just upgraded to Garage Sale Pro.
Can you please help? We just got our ebay selling back up after being down for 13 months because we made a major move across country and spent this whole month setting up everything (ugh).
