We are attempting to upgrade Tourbuilder Plugin using the opensource version. Currently items displayed on item map but not on the homepage map. Ability to create tours is also not present. When we try to upgrade the Tourbuilder Plugin we get an error message (screenshot 1 below). When we click the green ‘Upgrade’ button we get an error message “Omeka has encountered an error” prompt.
