Thanks for the advice. I did that and it worked when I reverted to version 7.11.40. I’ve got another website where your latest version works with Woocommerce, so it’s probably a conflict with something on that one website. Did you change anything substantial from version 7.11.41 that could have caused the conflict?
Solved. I just added my own custom slug for it and deactivated it that way.
Sorry this has been fixed. It was a plugin conflict.
