AAM Plugin

<p>ConfigPress is a development tool with the main intent to avoid any hard-coding and give an easy and flexible interface to manage all your website custom settings (options).</p>
<p>With ConfigPress you can define your own custom option or group of options and retrieve them in your code by simply calling ConfigPress::get(‘option_name’) method. This way you do not have to hard-code any sensitive or environment specific options in your custom code.</p>

ConfigPress

I copied the code for defining admin users from AAM to ConfigPress but that crashed the whole website. I had to delete the plugin to get access to the website again. As there's no reaction on my support mail to AAM since two weeks, I always have to switch of AAM and can not install ConfigPress, to change the user rights and roles. 
I will now search for another plugin which can restrict the access better and is more user friendly (the usability of ConfigPress and AAM is horrible, but in the past the functions were ok).



Doesn't work at all

Honestly I think that any rating system sucks. 99% times it is based on somebody's opinion which is always a subject for discussion.
So I rate myself 5 stars just because I can.



Why not

I think this is good plugin to easy manage some website options.
This is not really good solutions for clients, as they can broken something, but for developers that's fine.
Also I think need use helper function over this plugin for gettings settings, to avoid site down in case disabling plugin.

Simple but useful plugin

An easy way to manage all your website custom settings.
