I am having an issue with user accounts on my WP install.
During the check-out process (plug-in: wooCommerce), logged in users persistently experience this message:
"Sorry, that key does not appear to be valid."
(appears to log user out)
and takes the user to the following address:
[ my domain: scribblegraph.me ]
Any advise/tips? This is an annoying error for customers, I'd love to solve this one quickly.
Additional behaviour note:
· The order is actually successfully created, and expected email to vendor/customer is sent successfully
· clicking ← Back to scribblegraph DOES take the user back to a logged in account on the site.
