 * Hi there. I recently did a fresh install of WordPress 2.8. I installed Flickr
   Gallery 1.2.7 and immediately had problems.
 * On all pages, I got the following error at the top: (I replaced the full path
   with [root])
 *     ```
       Notice: Undefined index: action in /[root]/wp-content/plugins/flickr-gallery/flickr-gallery.php on line 105
   
       Notice: Undefined index: action in /[root]/wp-content/plugins/flickr-gallery/flickr-gallery.php on line 107
       ```
   
 * When I navigate to a category page, I also get this error:
 * `Warning: Cannot modify header information - headers already sent by (output 
   started at /[root]/wp-content/plugins/flickr-gallery/flickr-gallery.php:105) 
   in /[root]/wp-includes/pluggable.php on line 865`
 * On individual pages in which I’ve embedded the shortcode, I get this error at
   the top of the content div:
 *     ```
       Notice: Undefined index: extras in /[root]/wp-content/plugins/flickr-gallery/flickr-gallery.php on line 201
   
       Notice: Undefined index: extras in /[root]/wp-content/plugins/flickr-gallery/flickr-gallery.php on line 201
       ```
   
 * Just above the photos I embedded (which display fine) I get this error:
    `Notice:
   Undefined variable: photos in /[root]/wp-content/plugins/flickr-gallery/flickr-
   gallery.php on line 205`
 * I’m not versed in PHP, so any help would be greatly appreciated.
    Thanks!

 * Well I manually downgraded my WordPress to 2.7.1 and everything works perfectly.
   Thank goodness I didn’t have a lot of content to repost. Thanks again for writing
   this and phpFlickr!
