2 diffirent views of article, when caching is enabled

Hi, my problem on page drytooling.com.pl, are articles, with diffirent styles.

Here is example:

First picture is with good styles in headings



In second



Fonts on heads are diffirent (not squirel (bebas) fonts)

Page has turn on gvk cache
Joomla 2.5.11


Anybody has similar problem?

Please compare you cache configuration with this one http://www.gavick.com/documentation/joo ... ce-plugin/ probably one plugin is not enabled or the order is wrong. Remember always to clear cache to see results.
