Argument #2 is not an array in BxDolTemplate.php on line 480

I recently checked out my PHP log & found a slew of errors originating from BxDolTemplate.php.

Anyone have any idea what this means?

PHP Warning:  Invalid argument supplied for foreach() in /home/jabadoo/domain.com/inc/classes/BxDolTemplate.php on line 477

PHP Warning:  array_merge() [<a href='function.array-merge'>function.array-merge</a>]: Argument #2 is not an array in /home/jabadoo/domain.com/inc/classes/BxDolTemplate.php on line 480

Thank you..

This is what Lines #477-480 looks like..

foreach($mixedKeywords as $iKey => $sValue)
            $mixedKeywords[$iKey] = trim($sValue);

        $GLOBALS[$this->_sPrefix . 'PageKeywords'] = array_merge($GLOBALS[$this->_sPrefix . 'PageKeywords'], $mixedKeywords);

Hello

BxDolTemplate is used to parse dynamic content in HTML template. The error appears because some page passes incorrect parameters in the class especially in addPageKeywords method. The issue should be investigated to find the exact page and fix the issue in its code.
