The captcha plugin has been depreciated.

Please remove it and install CB Antispam.

I have deleted it but I still get white page.
Thanks

It wouldn't have caused a white page to begin with as it's just a strict standards notice. See the below regarding white pages, which is usually caused by memory limit issues.

Be sure debug mode and maximum error reporting are enabled in Joomla global configuration so you can see errors.
