Ii’d just like to further this issue as we’re experiencing something similar.
When the plugin is activated and a user is on a single event URL, then all of the href attributes in our main menu are removed. When not on a single event, the main menu is as expected.
i.e.
https://cawp.ubc.ca/
main menu works as expected. All links contain href attributes and can navigate around.
However, if you’re on https://cawp.ubc.ca/event/robot-made-large-scale-robotic-timber-fabrication-in-architecture/
which is a single event, you’ll notice the main menu no longer contains href attributes except for ‘Home’ (which is a custom link in the menu, specifically set to the home URL) and News & Calendar > Events Calendar link, which, likewise is a custom link in the menu. i.e. it appears to not affect custom links, but any Page added to the main menu appear to be affected.
Have you folks made any changes to the menu Walker class that might be affecting us like this?
This is also an issue on WP 4.8.0, PHP 5.6.
Turning on debug mode doesn’t throw up anything useful, just the initialization event in the error logs. Any thoughts?
