I have problems using categories in phocagallery 2.0.0 (with joomla 1.5.7): Adding categories and pictures in the backend works fine, but when I try to look at the categories on the webpage, I can just reach the first category level. When I try to enter the category in order to see the subcategories it just reloads the same side. Actually the adress seems to be wrong. When I change it manually to the subcategory ID it works fine:
First category address: /index.php?option=com_phocagallery&view=category&id=1&Itemid=2
Address, when I try to enter the category: (no index.php?)/tennisheim&Itemid=2?option=com_phocagallery&view=category&id=1&Itemid=2
When I manually change to /tennisheim&Itemid=2?option=com_phocagallery&view=category&id=4&Itemid=2 (ID 4 is the correct category ID in the backend), the subcategory is opened and I can see the pictures.
This is the situation with SEO turned off. When turning SEO on, I can still reach the first category, but when I try to enter I get "404 - Komponente nicht gefunden!" (Not found).
It would be great if someone could help!
I hope you understand my english and the problem description
