White page with just an ad loads

Greetings,

Some of the members on our forum( http://warhammerrejects.forumc.net/ ) have recently brought to my attention our newest annoying feature. I quote: 
"Alright, there's this odd circumstance that whenever my page refreshes/changes/whatever that the page breaksdown to a white page with a stupid add that'd normally be on the page
It practically runs on a 50/50 chance with how common it is, however going back a page is defrnate in being glitch free"

Further investigation revealed that it is supposedly a white page with only the ad block that would normally appear on the forum. Though i requested screenshots, and a list of devices this happens on, they failed to provide most of them so far. As such, all i know at the present time is that it happens on tablets and phones.(if there is a need, i shall use my mighty admin powers to squeeze the answers out of them)

Furthermore, i also acquired the following information:
"Go in a incognitio window, I had this all the time on my laptop before I got my new PC"
The laptop in question was supposedly a Dell one. However, this method does not seem to work for them.

Some assistance would be greatly appreciated.

Hello

I've checked your forum with a smartphone and didn't have any problem! If you can provide a screenshot it could be very helpful. Like that I will be able to show what's happen on your forum.

Thanks for your help

I shall issue the orders immediately.
I also dont have any such problem, but i assumed i was the exception since several people claimed to have encountered the issue.

Oh, mighty admin of forumotion. My underlings have returned to me with information:
The device in question is a Nexus 7 tablet(android)
However, they failed to provide a screenshot.... actually, i have no idea how to take a screenshot on a tablet either...
From what i am told, it is literally a blank, white page that has only the ad block of the site on it in its usual size.(the one right under the buttons bar)

At android you can make screenshot by pressing and holding screen lock and volume - buttons at the same time.

Thank you, random citizen

Another device that has the same issue is an iPhone 4. The following screenshot is from there:

Is this happening in mobile version or classic version?

Classic

Hello, I have exprienced this problem personally on my forum. I am using a tablet... it usually happens when it wants it..l then when I refesh it corrects the problem, I did not report it because I thought it may have been just me. The next time I see I will capture a screenshot for Buttercup.
