wp_cache_add( $user->user_nicename, $user->ID, ‘userslugs’ );

  • With version 6.6 & 6.6.1 I see this weird error. If Example was the username and example as the nicename, why is WordPress bothering the user? Moreover, when there is nothing that can be done from inside WordPress, where to approach? Isn’t it something WordPress should do on its own? This issue is baffling me. Please help me out!

    The full error is: Warning! wp_cache_add( $user->user_nicename, $user->ID, ‘userslugs’ );

    If unaddressed, will it create trouble in website functioning?

    Can you please inform what should be done? Currently am scared of using these two WP versions.

    Unfortunately, I can’t quite follow you. What is the exact complete error and at what moment does it occur? You would need more information to be able to reproduce this.
