[Plugin: Nav Menu Roles] Fatal error

What version of PHP are you using? What version of WP? Does this still happen if you disable other plugins? I cannot duplicate this locally or live, so I’m a bit stumped.

edit:

when stumped, turn to google. would you test out my version from github to see if this resolves your issue?

Hi, I resolve bug removing the & from &$output in the two lines:
parent::start_el( &$output, $item, $depth, $args );

Anyway, I change the code because I have conflict with my theme. The theme add ‘wp_nav_menu_args’ filter too.

Then I lose all menu format.

What I do is remove the ‘wp_nav_menu_args’ filter and register to ‘walker_nav_menu_start_el’.

And all work good.

Ok, that’s what I did to fix the bug too. I will push the update out to WordPress as soon as possible.

Does your theme use a custom Walker with wp_nav_menu_args ? Because otherwise the $args should just be merged.

Yes, it does.

This problem occurs not only with your plugin, I saw same conflict with all plugins that manipulate menu.

With yours, I understanding the problem.

Good to know. But yeah, you cannot use multiple Walkers. You could, however, adjust your theme to mimic the role-checking in my plugin.

please check out the 1.2 update. It uses an alternative method of restricting the menu items and will no longer conflict with a theme or plugin’s custom nav Walker.
