[Plugin: Events Manager] Blank Wp_admin Page

It worked fine for a couple of days. Then I had troubleshooting for all the day and in the end the only solution was to delete this plugin with ftp. I am really disappointed about it, also because when it worked it was fantastic. I have also followed the instruction on the plugin homepage, but there is nothing to do. Now WordPress accept only its version 3.0!! If I try to update it, I go back to a blanck wp-admin page…
