"Internal error" when creating an article

[nickfaarvang]

Whenever I create an article I get the following error:

"Internal error

An error occurred on the page you were trying to access. If you continue to experience problems please contact your Redmine administrator for assistance.

If you are the Redmine administrator, check your log files for details about the error."

I can create categories and sub-categories just fine. I have not been able to find a similar issue described anywhere.

@nickfaarvang I'm assuming you installed the redmine_contacts plugin first, as this also includes a tagging library. I'm looking into better way of handling this as it's a recurring issue...

@alexbevi I am having this same issue and I also have the CRM light contacts plugin installed. Is this issue resolved by uninstalling the contacts plugin and then re-install the knowledgebase plugin? Are there any other workarounds?
