[Plugin: Wordbooker] Random meta code?

Hi,

I must say I am really pleased with this plugin – only there appears to be one glaring problem. On this page of my website http://www.screencult.com/services/ there appears to be this random bit of code:

wordbooker_options: a:8:{s:18:"wordbook_noncename";s:10:"01be3b066d";s:18:"wordbook_page_post";s:12:"100345981582";s:18:"wordbook_orandpage";s:1:"1";s:23:"wordbook_default_author";s:1:"3";s:23:"wordbook_extract_length";s:3:"200";s:19:"wordbook_actionlink";s:3:"300";s:18:"wordbook_attribute";s:35:"Posted a new article on their site ";s:29:"wordbooker_status_update_text";s:35:": New blog post : %title% - %link%";}, a:8:{s:18:"wordbook_noncename";s:10:"01be3b066d";s:18:"wordbook_page_post";s:12:"100345981582";s:18:"wordbook_orandpage";s:1:"1";s:23:"wordbook_default_author";s:1:"3";s:23:"wordbook_extract_length";s:3:"200";s:19:"wordbook_actionlink";s:3:"300";s:18:"wordbook_attribute";s:35:"Posted a new article on their site ";s:29:"wordbooker_status_update_text";s:35:": New blog post : %title% - %link%";}

With Firebug, I was able to see it was pointing to some post-meta but I didn’t put in any custom fields. Needless to say, I went to the page and went to add a custom field, to see and lo, in custom fields there is an option to pick ‘wordbooker_options’ – why is this? When I added it, the Custom field panel doesn’t show it is there (like it disappears) but it appears on the page. Is it hidden or something? I don’t know.

Needless to say, I deactivated it and deleted the plugin and annoyingly the code is still there!

If anyone can help, please do, as we have many of our clients coming online to have a look!

Many thanks in advance
