I would like to know if I could enable amember4 plugin in two wordpress blogs installed in a same domain. for example, one wordpress blog installed in the root, viz., www.domain.com and another in a sub-folder, viz., www.domain.com/folder
Just install amember plugin into each wordpress installation and link each plugin to your single aMember installation. There should not be any issues in such setup.
In amember plugin wordpress i have selected the wordpress Hère amember/admin-setup/wordpress How to add à second wordpress ?
do you mean how to add second wordpress plugin into amember? This require customization. Contact us in helpdesk we will send modified files.
I also want to use amember4 to control access selected content on two separate wordpress blogs. Both blogs are on the same server... although they are in different domains. One is personallifemedia.com and the other is members.personallifemedia.com. Can I set it up that way... or will I need to move one to a folder (instead of a sub domain)? I understand that we'll need two wordpress plugins and will need to contact support to get the modified plugin. Thanks in advance for your advice.
Sure you can have second blog on subdomain. Here is how you can create duplicate wordpress plugin: http://www.amember.com/docs/How_to_link_aMember_to_different_wordpress_blogs
