After visiting ../admin/structure/context/xx_xx_xx error logged the following, The "superfish:main" was not found.
Uninstall Superfish on a site with the Context module installed. I can not tell you whether or not the context had a Superfish block, though I'd hope it would have been gracefully removed during the uninstall process.
Enabling the Superfish module and visiting the same page and there is no error.
Uninstall Superfish, and the error is there again after visiting the page.
