I purchased Premium version Responsive Lightbox – Masonry Image Gallery, but when I try to activate, Responsive Lightbox & Gallery’s licence setting page tell me “1 license activation failed.” And I click Add-ons tap of Responsive Lightbox & Gallery’s setting page, the page tell me “There was an error retrieving the extensions list from the server. Please try again later.” I use web hosting service Blue Host.
I have another web server on my own computer. On this computer, all works normally. Activation and clicking Add-ons tap are successfully without any other error message. How do I do? Premium version Responsive Lightbox – Masonry Image Gallery is not compatiable with Blue Host WordPress service? Please help me.
