Tabs GK5 not working on iPhone/iPad

Hi guys

I have an interesting problem with the site on Events template. These funny tabs on the main page are not working fine - on your demo site this the section called Upcoming events. When I open the site on iPad or iPhone for the first time, this module is not working and so is the menu - it's completely dead. However if I open anything else on the site, like an article, and then go back to the main page, everything runs smoothly. As far as I'm aware the problem occurs only on Apple devices and it's always not working until you do something else on the site - then it somehow starts running fine.

The website was installed from the quickstart and then customized, but everything was done according to your guidelines - there is nothing suspicious there, no millilon modules, just the cookies plugin really. I thought it was its fault and I tried installing 4 different cookie plugins and the problem was the same. Even after uninstalling all cookie plugins it was still like this. So I thought it may be something with jQuery so I installed jQuery Easy - nothing, and then eorisis jQuery - nothing. The website in question is www.radiojazz.eu.

Any ideas? Please help.

To sum this up - same happens on our demo server?

Nope, on your demo website it all works fine. But my website has been installed from your quickstart and as far as I know, nothing really sensitive has been changed by me. Could it be some out-of-date software on the server? It would be interesting because I now have two copies of this website - one on the client's server and one on my own - both are completely different, run by two separate providers.

What version of iPhone (model and os version) do you have?

Hmm... The problem has fixed itself with iOS 9;-)

Maybe it was some kind of weird cache issues... It's ok that it works now.
Is there anything else I can help you with regarding this topic?
