    Hi Nicolas,

    Sorry, I know this is not the matter of your comment but I didn’t find where to ask for help.
    i have just started using “OptimizePress Landing Page” software and I found that it doesn’t work with “Customizr” theme….
    I have tested with another theme and the landig page work fine.

    Is there any issue with Customizr and landing pages? How can I fix it?

    Thanks in advanced.
