Unfortunately, this doesn’t work for me. When I select the image, the preview is rendered. Nothing happens, when I want to save my changes. It seems to be, that instead of textual content, the right image reference isn’t inserted in the database.
The problem may arise due to an incompatibility with certain PHP or MySQL versions. On my host, I got the following configuration:
MySQL 5.0.32, PHP 5.2.17, Apache 2.2.11, WordPress 3.4.2
On my localhost, I have this config, which works fine for me:
MySQL 5.0.8, PHP 5.3.8, Apache 2.2.21, WordPress 3.4.2
And yes, I already reinstalled organize series and deactivated all other plugins.
