Hi balgev,
really this is difficult issue, i checked your site on some tool and see there are some problem below :
1. Your site use more images and the image size is very big.
2. Use more module and plugin to request from other site(twitter, facebook,…)
3. The content in your site is more..
i suggest you use some site to check site performance(http://www.webpagetest.org , http://websiteoptimization.com ,…) and get comment from it to reduce load time of site.
About content can’t load in site, i see the blank page in ja news module, please send me admin account via pm, i need it to have a close look on it.
Hope can help you 🙂
