We're running WP 3.8.1 and Meta Slider Pro 2.3.2. Everything works fine, but as soon as we activate Gmedia Gallery then Meta Slider stops working. The area with the slider shows up blank. (Note: there is no Gmedia Gallery on the same page as Meta Slider.)
When you deactivate Gmedia Gallery and clear the cache, Meta Slider works again.
I compared the code with and without Gmedia Gallery activated and there is only one distinction: when Gmedia Gallery is activated, the following code appears in the head on every page (including the page with Meta Slider)...
(I've substituted "mydomain.com" for the actual domain name.)
