Precondition Failed when publishing PHP in static content - Joomla! Forum - community, help and support

-

i error
"precondition failed: precondition on request url /joomla/administrator/index2.php evaluated false."
whenever try save php code within body of static content item.

i've tested php code on non-joomla site , works without errors.  i'm not using wysiwyg.  i've tried using extensions "runphp" , "mossnippet" both of claim allow php within content items, haven't had luck either of them.  same error when try save using them.

does joomla not support php within content?  or there solution i've overlooked?

thanks,
karen
