Hi,
A new version of the CKEditor Integration is available. See https://extensions.xwiki.org/xwiki/bin/view/Extension/CKEditor%20Integration/#HReleaseNotes . This new version fixes some regressions found in the previous version thus we highly recommend upgrading from 1.24 to 1.25. This version will be bundled with XWiki Standard 10.7 but you can also install it on older versions of XWiki using the Extension Manager.
Enjoy,
Marius
