CKEditor 3.5.4 that ships with the current versions of Couch (1.2.5 & 1.3RC1) has been reported to have problems on Chrome 18/20 in displaying the image explorer for embedding imageshttps://dev.ckeditor.com/ticket/8855https://dev.ckeditor.com/ticket/9069
CKEditor 3.6.3 fixes the bug.
Additionally, it also supports HTML5 tags.
To upgrade to 3.6.3,
1. Download the attached 'ckeditor.zip' file. Unzipping it will yield a folder named 'ckeditor'.
2. In your existing Couch installation, please find and delete (or rename to something different) the 'couch/includes/ckeditor' folder.
3. Upload the folder unzipped above to 'couch/includes/' to replace the original folder we deleted above.
Also attached is the 'lang' folder for languages other than en, fr and de.
