 * Hello developers,
    I use this plugin and have on the server PHP 5.5 and the last
   version of MySQL. But after the last update of EU Cookie Law comes this error
   message:
 * `Warning: Can not modify header information - headers already sent by (output
   started at /www/htdocs/xxxxxxx/wp-content/themes/fashionistas/header.php:11) 
   in /www/htdocs/xxxxxx/wp-content/ plugins/EUCookieLaw/class-frontend.php on line
   15`
 * I do not know what it is and need your assistance. I’ve been using the last version
   of WordPress. Thank you in advance.

 * Hi Alex,
    does this happen on every page load?

 * Hello there,
    I have reactivated the plugin and in the backend this Notice is
   displayed:
 * `Notice: Undefined index: port in /www/htdocs/xxxxxxxx/wp-content/plugins/eu-
   cookie-law/defaults.php on line 50`
 * In the frontend when I call other pages and blog posts, the error message is 
   gone. But immediately after activating the plugin still an error as described
   above was displayed. Whether it really has to do with my WordPress Theme Fashionstas?!

 * Just ignore it if you see it the first time only. I will release a fix as soon
   as possibile.

 * Hi,
 * and thanks for the quick elimination of the error. I have looked over it again
   and now see no more errors in the frontend. Everything seems to be working.
