[SOLVED] Too much content -> page empty

Please let me first say Thank You! and my congratulations for this great theme! It is the best theme I have ever seen.

I have just one little problem: On my website I wanted to have two single pages with literature tips. So I styled one with books and one for articles. Both with pictures of the books / articles and links for download or further information.

The second page now causes some problems: If the is too much content (perhaps too many pics?), the page turns to an empty page.

I solved the problem by creating three (sub-)pages, but I am not glad with this. Because the articles are in chronological order. So, if I have to add a newly published article, I do this on the first page for articles, called "Fachartikel" (http://variable-verguetung.de/literatur/fachartikel/). You can see there is a new one, in red letters and in German "NEU". After saving, the page is empty.

So I have to cut out the last article (picture and links) of this page and put it on the next page ("Fachartikel 2"). After saving Fachartikel 1, the page is normal and everything is good.

But now Fachartikel 2 turns empty. So I have again to cut out the last and transfer it to "Fachartikel 3", save Fachartikel 2 and Fachartikel 3 and everything is good.

That´s how you see it in the moment.

But I really would like to see all articles on one page... Can you help?
