problems with large items

I just purchased and installed the template News World II, but I have a serious problem as long items, over 50 pages, can not be read, leaving the page blank.
If the cache active GK items appear long, but duplicated in the same space, that can not be.
can you help?

You probably don't configure cache plugins properly, please look here >> https://www.gavick.com/documentation/jo ... ce-plugin/

I installed the plugins GK and GK ExtCache Cache plugin, I set the template, I cleared the cache expired in joomla administrator, but the problem persists.
You can visit this address and check that you can not open a text file, which opened with the above template

I need to know honestly if the template can handle large text files, otherwise you'll have to leave this template, I like both.
