[Plugin: TDO Mini Forms] Error message on installation

Hi Guys

I am running latest version of tdo and WP3.1. I’ve just installed the plugin and get the following error message, (I did try and change the session management settings and even set chmod up to 777. The folder structure is standard – any help would be appreciated:

Error: Got a 0 error when checking https://www.maldon-town.com/wp-content/plugins/tdo-mini-forms/tdomf-form-post.php! This will prevent posts from being submitted. The permissions may be wrong on the tdo-mini-forms folder.
Error: Got a 0 error when checking https://www.maldon-town.com/wp-content/plugins/tdo-mini-forms/tdomf-form-ajax.php! This will prevent forms that use AJAX from submitting posts. The permissions may be wrong on the tdo-mini-forms folder.
Error: Got a 0 error when checking https://www.maldon-town.com/wp-content/plugins/tdo-mini-forms/tdomf-style-form.css! This will make your forms, by default, look very ugly. The permissions may be wrong on the tdo-mini-forms folder.

Thanks
