Hello, I'm using the Add-on Builder since 7 days. In my "private addon" section, I have 16 add-ons (Add-on projects). URL here: https://builder.addons.mozilla.org/user/private_addons/ When I try to list the projects nr. 11-16 I click on the Link labeled with "Next"(on the bottom of the site). But Add-on Builder isn't able to show the site. Instead a blank page appears with the message "500: Server Error" in it. I am a new user since a week, and the problem exists since a week . -Is it a bug?
