Blank Modal on add location

when i click on add location i get a blank all white modal/popup with no content...
Not sure why this has happened everything was working fine...

In error reporting(developer) i see this in the modal

Fatal error: Uncaught Error: Call to undefined method Error::setProperties() in /home/cumbriat/public_html/plugins/system/koowa/koowa.php:169 Stack trace: #0 /home/cumbriat/public_html/plugins/system/koowa/koowa.php(142): plgSystemKoowa->errorHandler(Object(Error)) #1 /home/cumbriat/public_html/plugins/system/redirect/redirect.php(112): plgSystemKoowa->exceptionHandler(Object(Error)) #2 /home/cumbriat/public_html/plugins/system/redirect/redirect.php(91): PlgSystemRedirect::doErrorHandling(Object(Error)) #3 [internal function]: PlgSystemRedirect::handleException(Object(Error)) #4 {main} thrown in /home/cumbriat/public_html/plugins/system/koowa/koowa.php on line 169

i tried disable koowa and get a 404 in the modal..?

Thanks for your help.
Regards,
Shaun
