UPME shortcode problem

Hi,
I have a problem with UPME plugin. Shortcodes, that I’m supposed to add to a page, break those pages. All of them except,[upme_login].
The pages show only header and page title and nothing else below, including other content and footer. I tried to put [upme_login] too on other pages, it works only if [upme_login] is placed above other shortcodes, if it’s placed below other shortcodes, same blank space appears.

I tried to activate various themes, it is always the same. I deactivated all other plugins, nothing’s change …
