Thanks @khalwat. I shall have to review that template and see where it is different from the others. I'm intrigued though why the cache clearing causes a problem in one case and not the other. Hopefully I will find the reason in the code.

<p>I have this line</p>

Is it bad practice to re-use array variable name?
