No prob, lil bro.

And you have to create the mu-plugins folder now.

The plugin you refer to will change certain settings when you register a new blog, therefore old blogs won’t be affected by this plugin.

For mu-plugins folder, you can add plugins whenever you want, just like the normal plugins folder, except the plugin is automatically activated.

“New Blog Defaults” <- I am SO glad you mentioned this plugin, because I didn't know about it.

The readme file on this says: "Settings will only affect new blogs". Does this mean that all MU plugins that we intend to use should be included at the time we perform the install of WP, or else it is too late?

I appreciate the lightening fast reply and explanation: “put the plugin file itself directly in the mu-plugins folder, not its enveloppe folder” – and wow it appears.
Great! Thanks

PS : my first comment entry automatically generated a twitter link but its an invalid one??

oops, code won’t work with php tags…

the file would contain this line inside php tags:

include(‘login-with-ajax/login-with-ajax.php’);

that’s it

yes, exactly. Just a normal php include will do.

I’ll give my login with ajax plugin as an example. Just move the login-with-ajax directory into the mu-plugin folder and create the following file in the mu-plugins folder:

wp-content/mu-plugins/login-with-ajax.php :

That’s it. WordPress will now auto-activate this plugin.

Great, thanks for the info.

By “include” you mean a simple php include? Can you, please, give an example?
