I’ve just purchased and installed Sangar Slider after running into a conflict between FR Slideshow and WooCommerce.
Now that I have the slider plugin installed, I am getting a message at the top of the screen that reads:
"Please enter your Sangar Slider licese code in Options Page"
When I click the "Options Page" button, I just get a page that says "Loading…".
I am running WordPress 4.8. But I am unable to enter the license key in order to use the slider.
