I use the plugin domainmapping for 1 year and I have never had a problem, however I recently changed server (ubuntu & plesk & wordpress 4.1 multisite) & and since the settings are not the same and I encounter two problems main:
1 / redirection from running properly to the domain name, for this to work I have to enter the domain name in plesk before that the domain name was redirected with the plugin
2 / I parameter only the A field in the DNS domain (for example, website.com A 112.585.96) yet the submission form emails from the domain name to an email domain (example: contact @ website com) does not work.
Is what I missed a step in the setup? then I fixed this?
Thank you for your help.
