Problems with "Slider Service" and Media Gallery

wordpress

#1

I use theme Photology v1.0.3
I didn´t change any code just changed demo-file and added sliders.
Slider cannot be loaded in Safari and Chrome. Only “loading-image” appears.

2nd problem: Media Gallery:
I set “Partial load image count” to 15. Galery has 150 images, but only first 15 are shown. Rest is not loaded anymore.

Has anyone an idea what could be the problem?
