Page crashing on iphone

Hello
First of all let me say I love this plugin, it does exactly what I need it to do.
My issue is that it creates some kind of redirection that only in iphones crashes the pages where it’s installed. I’ve tested deactivating the plugin and the page works just fine in iphone, but with the plugin activated I get the message “a problem repeatedly occurred on the page”.
I’m not a developer and my knowledge is very limited, just so you know.
Is there a known issue with iphones or a way arround it?
Thank you very much!
