Proper with "Executing Custom PHP Code" Action I am trying to add an action that &quot;Executes Custom PHP Code&quot;. I click Add a new action to the rule I have created and I choose &quot;Execute Custom PHP Code&quot; 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: &quot;Missing configuration for parameter code.&quot;

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)
Thanks
Conor
Okay I solved it, It turned out to be very simple. Facepalm

I had misconfigured nodejs which was causing a javascript error. Which meant the textbox which should've appeared didn't.

I reconfigured nodejs and it worked fine :)
