LH Number User Nicename


This plugin overwrites the user_nicename for WordPress users with the user ID, this creates an extra level of security.

It also ensure every user has a url even if they have not authored a post.

Admins can also edit the user_nicename in the backend.

What is something does not work?

LH Number User Nicename, and all plugins are made to WordPress standards. Therefore they should work with all well coded plugins and themes. However not all plugins and themes are well coded (and this includes many popular ones).

If something does not work properly, firstly deactivate ALL other plugins and switch to one of the themes that come with core, e.g. twentyfirteen, twentysixteen etc.

If the problem persists please leave a post in the support forum: . I look there regularly and resolve most queries.

What if I need a feature that is not in the plugin?
