Hello.
Home blog is correct, holds up in the template. However, if you select the option 'categories' or 'users' to the following breakdown (damage) Joomla template.
Best to see it on my test page.
http://pastel.nazwa.pl/ro-uslugi365/blogi-firmowe - correct appearance
http://pastel.nazwa.pl/ro-uslugi365/blogi-firmowe/categories - template broken
Where to find the cause of such behavior?
What causes these changes?
