    After I updated to AddThis Version 2.0.3, I am getting following warning message while posting or updating a post:

    Warning: Cannot modify header information - headers already sent by (output started at .../wp-content/plugins/addthis/addthis_social_widget.php:1168) in .../wp-includes/pluggable.php on line 897

    Can somebody help me solve this problem?

    There was a compatibility issue with (at least one) other plugin that I think you are running into.

    I've updated the development version and I think I've fixed it. if you go to https://wordpress.org/extend/plugins/addthis/download/ and click Development Version, you can get the latest version. Let me know if this resolves it for you. If it doesn't, can you let me know what plugins you have installed so I can investigate further.

    Thanks, Aaron

    Maybe you should fix your own errors first before blaming an other plugin?

    like the one on line 200 and 492

    I'm sorry if you feel as though I'm blaming the other plugin, that certainly wasn't my intent. I mention that it is a compatibility issue because it only occurs when the other plugin is also active.

    As I mentioned in your other threads, the two errors you mention have also both been fixed in the latest development version.

    Thanks, Aaron

    Thank you for suggesting to use latest development version of addthis. I have switched to this version and error has stopped appearing.

    I am using some 15+ plugins ranging from SEO to tagging to database backups.
