    AttributeError: 'str' object has no attribute 'text'

Steps to reproduce:: Probably bad migration / mismatching file system version in some point. Cannot know the conditions triggering this issue.

Monkey-patch to work around the issue:

    from Products.CacheSetup.content.base_cache_rule import BaseCacheRule

    def getVaryExpression(self):
        expression = self.getField('varyExpression').get(self)
        if expression and hasattr(expression, "text"):
            return expression.text
        if expression:
            return expression

    BaseCacheRule.getVaryExpression = getVaryExpression
