Hello !

I have two communities : one which was created with IPB4 and the other which was upgraded from 3.4 to 4.1.8.

The first community appears normally on my iPhone, but the one I upgraded uses only half the space and the menus don't work :

How can I fix this in your opinion ?

Thank you !

First, post the forum url and give people a chance to see the issue.

Here it is :

Can you tell me if you have the same problem ?

Thank you.

Anyone who minimises their browser down, or uses a mobile device, will have the problem - scroll to the bottom of your site and look at the ad above your footer. Remove it and I bet things work fine.

Or get responsive ads https://support.google.com/adsense/answer/3213689?hl=en

Thank you. You were right, the banner was the problem... I tried the responsive ads and it seems it's ok (but I notice it doesn't appear in Firefox).
