Hello.
Since we updated Event Espresso to 5.0.10.p, we are getting the following PHP fatal error when an Editor logs in.
Also, all WordPress dashboard screens become white and non-functional.
Can you check if you can reproduce this issue?
Please advice on how to fix this.
Thank you.

Hi there,
I can’t reproduce this but it looks like something is setting up menu/submenu items incorrectly on the site so it likely depends on the plugins you have active.
The error is from EE expecting some kind of string value (a capability) to be passed to current_user_can() but it is passed NULL which isn’t expected. A WP core function used to display the menu within the dashboard is processing the menu items and then passing a capability as null so somewhere along the line something is setting up menu items incorrectly.
I’ll check in with our developers on this.
