 * Since today I noticed a problem on my site using the eventlist widget:
 * on my site the plugin gives me this error:
 * Please visit widget admin page and press “Save” to perform the required widget
   updates (required due to changes in new plugin version) !
 * In the backend it’s fine till I want to save a new event. Then it gives me this
   error
 * Warning: Cannot modify header information – headers already sent by (output started
   at (website)/wp-admin/includes/template.php:1698) in (website)/public_html/oo/
   wp-includes/pluggable.php on line 896
 * I already tried reinstalling but that didn’t work. Can you help me?

 * Sorry, I have no idea why it isn’t working for you. I think I have to improve
   the error messages soon to allow better support for those problems.
