Hello!
I have my own setup where I can test the mod over, so no access to your server will be needed for the dev.
I pulled the plugin already from wp repository, assuming you have the same version and that you have not already made other changes to it, so I can look at the code.
You need both the sneak-peek months count as well as the on disabled message as plugin ontions I guess?
I'll get back to you as soon as I have gone through teh code, or in case I have any further questions.
Kind Regards,
Dobri
