register_uninstall_hook was called incorrectly

Hello Team,

When I try to publish a new post on wordpress, the page times outs after 60 secs. It given 504 page time out error message. I tried debugging and I get the following error messages.

Notice: register_uninstall_hook was called incorrectly. Only a static class method or function can be used in an uninstall hook. Please see Debugging in WordPress for more information. (This message was added in version 3.1.0.) in /opt/bitnami/apps/wordpress/htdocs/wp-includes/functions.php on line 4161

After I disable the androapp, this message no longer comes but the time out problem still exists. All this started after the latest udpate of wordpress.

Please help.

Regards,
Sasidhar
