Besides upgrading to the latest versions of tinyMCE and jQuery as well as Pagemanager_XH, there were some minor bugs fixed and some small improvements made. For details see the roadmap archive.
- Upgrade from 1.5 to 1.5.6 (follow the upgrade instructions)
- Upgrade from 1.5.4 to 1.5.6
Upload the new files in the cmsimplexh folder over your existing 1.5.4/1.5.5 installation, and change the setting of "autoload" in the configuration of the jQuery Plugin. As always we recommend making a backup of your website before upgrading.
