Something has gone wrong: MultiValueOperand not found in the function registry. Returning an empty query.

We get this error while calling a scripted JQL Function in JIRA 6.3.10, Script Runner Version :

jira.groovy.jql.ScriptedFunctionClauseFactory Something has gone wrong: MultiValueOperand not found in the function registry. Returning an empty query.

It worked before upgrading the Server from JIRA 6.3.1., Script Runner Version 3.0.3.

What can we do about it? How do we get it into the Function registry? In plugins/servlet/scriptrunner/builtin?section=script_functions#, it says

Not initialised properly

can somebody point me to the right documentation for this?

I haven't seen that befpre - in the first instance can you try just disabling the enabling the plugin, if that doesn't work restart jira.

Do any other functions work?

If all fails can you get me the log from startup and including this failure...
