I think that this error has nothing to do with the extension.

PHP Warning: in_array() expects parameter 2 to be array, boolean given in /htdocs/includes/parser/ParserOptions.php on line 297

Seems like there is a wrong in_array call in the ParserOptions.php on line 297, 302 and 317

Looks like my last comment was total crap.
But I have the same problem with the DynamicPageList extension.

I maintain DPL and I think the problem lies in ParserOutput.php, line 339.

function getUsedOptions returns "false" if no options exist, but later in ParserCache.php, line 186 the result is passed to ParserOptions.php, function optionsHash(..); This function is not aware of the fact that its argument might not be an array.

I suggest the following BUGFIX:

/**

• Returns the options from its ParserOptions which have been taken
• into account to produce this output or false if not available.
• @return mixed Array/false

	 */
	 public function getUsedOptions() {
		if ( !isset( $this->mAccessedOptions ) ) {
			return array();  // BUGFIX: return empty array !! 
			return false;
		}
		return array_keys( $this->mAccessedOptions );
	 }

This bugxif works with DPL and I am pretty sure it will also avoid the same error with any other extension ....

Gero's solution fixed my wiki's problems, any chance of this being included in 1.18 so we don't have to keep patching it?
