VM 2.0.26a - ERR_EMPTY_RESPONSE in edit billing address

[DCJunior]

Whenever a user attempts to create an billing address or even edit it, results in ERR_EMPTY_RESPONSE

However if I try to do that as an administrator, works perfectly.

Please help me, my shop is closed for this problem.

I cannot find this string in my project or extensions. Which extensions do you use?

Since I upgraded to VM 2.0.26a I have exactly the same problems in some websites.

For instance here: http://www.debruidslakei.nl/trouwjurken/lilly
All other webshop pages work fine but this category keeps resulting in a ERR_EMPTY_RESPONSE
