I'm using your slider up until now without problems. My use case up until now was to create some sliders and insert their shortcodes into individual pages.
However, this morning I was thinking that some pages need specific slider, while the rest should use the same slider. So I set the Global ID setting to be the slide I want to be global. Ever since things don't work anymore :(
Every page displays the following error:
Notice: Undefined index: vegas_isglobal in [...]/vegas-fullscreen-background-slider/index.php on line 296
After receiving this error I tried to make the Global ID setting empty again, hoping this would revert whatever went wrong since using it, but alas, the plugin won't work anymore, insisting that something went wrong.
I looked through your code but my PHP and especially WordPress knowledge is way too much lacking to do anything useful with it. Do you have any idea what's happening?
Also, I can live without the global slide, so anything to make the individual slides working again would be great ATM.
