Hi,
This problem is just like the one mentioned in http://www.zenphoto.org/support/topic.php?id=1372595

I am using the zpBase theme, it is slightly modified.
Everything was working fine, i had the masonry layout and infinite scroll on auto, then my partner viewed the site on her laptop and it appeared to be displaying the mobile layout (standard grid with pagination etc). I saw she had the latest version of Chrome (version 41) and i had version 40, so i upgraded and the same thing happened to me.
If i turned off the "Mobile Force Default Grid" option and i get the masonry layout but the infinite scroll doesnt work so i only get the first lot of pictures displayed with no way of seeing any others.
When testing on another computer using version 40 of chrome i get the masonry layout even with "Mobile Force Default Grid" on but still no infinite scroll.
I have tried clearing cache on all computers i've tested it with, cleared the cache in zenphoto, i've used IE, i've tried using the default zpbase theme to make sure i didnt mess something in one of the files and it all does the same thing which leads me to believe i havent messed anything up.

I can give the link if anyone would like to test on their machine.
Does anyone have any ideas? Its as though the detection of a mobile device and/or javascript isnt working properly, but why would this suddenly stop!?

Thanks,
Alex

I have added the theme name to the topic so the theme author will see it.

Thank you acrylian.
Now IE is working fine, but still no joy in Chrome. It still thinks its displaying on a mobile. Very odd problem!

Updated the Mobile_Detect script.
Works for me now.

Please try the Support build.

Thanks fretzl. Your update appears to have fixed it for me.

Thanks very much for a quick solution
