 * Hi
 * I’m receiving the following error on my page after installing a plugin called‘
   Advanced Access Manager’
 * I read somewhere i need to wrap something in an ‘if statement’ but have no idea
   what or even it this is the correct solution. I’ve checked the forums for the
   above plugin and found this link [http://wordpress.org/support/topic/plugin-advanced-access-manager-ouch-killed-my-testing-site?replies=2](http://wordpress.org/support/topic/plugin-advanced-access-manager-ouch-killed-my-testing-site?replies=2)
 * But this refers to another plugin not web-scraper.
 * Can anyone help…certain pages on my site just look blank because of this error.
 * Thanks
 * Jay

 * obviously multible plugins try to extend the class Callback with CallbackBody–
   check your pluginsfolder for the string CallbackBody
    und remove one of the plugins
