I like the idea but when I install this plugin, immediately at the top of the plugin screen after the install, I get this error.
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/25/5853525/html/wp-content/plugins/timeline-for-categories/timeline-for-categories.php:1) in /home/content/25/5853525/html/wp-content/plugins/tumblrize/tumblrize.php on line 58
I figured it had a problem with my Tumblrize plugin so I deactivated it. When I did, I then get the error mentioned in the notes
The plugin generated 3 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
So I disregard it like the notes say but when I go back to my categories and try to put them in chronological order, I get
Warning: Cannot modify header information - headers already sent by (output started at /home/content/25/5853525/html/wp-content/plugins/timeline-for-categories/timeline-for-categories.php:1) in /home/content/25/5853525/html/wp-includes/pluggable.php on line 881
I didn't carry it further this time but a while back I was messing with this plugin and disregarding the error messages but every time I added a category, it threw an error message. So I backed out and deactivated it.
I love the idea but hopefully it can get fixed.
