Mobile settings.

My members cant access chat and other features on their mobiles???

Is there a setting or something for this??

Thankyou

the phones need flash ... I think this would be the issue!

I have entered my own chat and chatted using mobile phones before and I have other members that do it also.

Most of my members that I know use their phones use the phone web browser so the site looks and works just like on regular computer except they type on phone dial pad and not regular keyboard.

As noted above, the Chat and Messenger modules use Flash, which Android (since Jelly Bean) and iOS don't support.  Only some older Android phones ship with Flash - Adobe no longer develops or supports it.
