I am trying to add an action that "Executes Custom PHP Code". I click Add a new action to the rule I have created and I choose "Execute Custom PHP Code" from the drop down the loading spinner appears for a couple of seconds and then disappear. The only thing I can do is click Continue which does nothing.
Then when i navigate to another page I receive the follow error
Value field is required.
The integrity check failed with the following error message: "Missing configuration for parameter code."
Has anybody got any idea why this is coming up.
It sounds like a box is supposed to appear but it doesn't.
As far as I can see I have all the right modules installed. (PHP filter, Rules, Rules Scheduler, Rules UI, Trigger).
Oh I am using Drupal 7.7 (I am planning on upgrading to 7.8 later today)
