Hello,
i have some problem with your key license of add-ons for Supermap, Responsive Slideshow and Power tools.
When i insert my license key and i save the setting page into my wp admin area i get this message:
A variable mismatch has been detected.
I noticed also that there is a 404 error:

Do you have any ideas to solve my problem?
Thank you in advance
