Weird layout and COM_VIRTUEMART_CAT_NOT_FOUND

[hisslink]

Hi! After a few months of inactivity, I re-activated the website justcarry.nl. The frontpage works just like normal, but all the pages that have Virtuemart content, look weird (for example: http://justcarry.nl/draagconsult-draagdoekconsult-breda-tilburg-roosendaal). Do you have an idea why this is happening? I tried updating the component, but that didn't help.

I see a failed reirect page - like an .htaccess problem.

Excuse me. This is another example: http://justcarry.nl/index.php/ergonomische-babydrager-draagzak/ergobaby-babydrager-draagzak-babycarrier-drager/ergobaby-heart-to-heart-verkleinkussen-organic-detail
I'm using Joomla! 2.5.11, Virtuemart 2.6.22 and PHP version is 5.3.28.

Can anyone help me out on this case?

would help if you give some example of what it is supposed to look like as opposed to "weird"

add to cart etc is broken with a 500 error, your versions are very out of date,

you don't say what you have done to the site recently or if u are using some useless 3rd party SEF component etc etc
have u tried with SEF off?
