What do you mean by custom fields?
Also could you provide some more details like the revelant part of the error log?

[rlohaus]

You can create custom_fields on Administration - Custom Fields , and add on issues on every project.

When add redmine_hipchat_per_project plugin, update issues of any data on "user_defined" field created on Custom Fields produces an 500 Internal server error:
