I recently installed Meta Slider onto a new WP Site. Played around with it and its excellent, and was considering getting the Pro version until I encountered a major problem.
When I now click the 'Meta Slider' menu on the left-hand side, its just a blank page - the header slider that I created previously still works (http://slddesign.com/blackriver3).
When I delete the 5 slider images from the WP Media Library, and click on the 'Meta Slider' again, the slider I created is again visible - minus the slides. But if I add any image/s this issue reoccurs.
I'm not using any other plugins. Although I'm using a custom theme, I've reverted back to the 'Responsive' theme but the issue also occurs in this theme - so its not a theme related problem either.
I went through your 'The Top 5 Meta Slider Issues' post, but nothing there resolved the issue.
For my client I'm looking for a slider product that is a) responsive, and b) allows you to define multiple sliders. Your product ticks both boxes, and if you resolve this issue, I'll definately upgrade to the pro version...
