I have four custom menu's: primary, sidebar, header, footer.
I changed the name of a page from 'Laufanalyse' to 'Laufanalyse, Sportberatung'.
In the custom menus primary and sidebar I edit the appearance/link name to be 'Laufanalyse' (The name the page had before).
Now the primary and sidebar menu slots are broken. No matter what,
<?php wp_nav_menu( array( 'theme_location' => 'primary','link_before' => '<span>', 'link_after' => '</span>' ) ); ?>
now lists all the pages the site have. Sadly, this is also true for all new Custom Menus I create. Only the Header and Footer menus still work.
How do I fix this?
