Wyvern is built to provide the best content entry workflow possible. It is the first and only editor that integrates seemlessly with all of these popular modules: Structure, Pages, Taxonomy, NavEE*, SafeCracker/Channel Form, and Assets. It was the first ExpressionEngine editor to include a visual editing mode to see separations in your content blocks so your editors do not get confused and mangle the content.

Update from EE2

If you are updating a site from EE2 to EE3 you probably run into some trouble with Wyvern. To fix the issues, you will have to follow the following steps if you have some kind of PHP errors.

  1. Navigate to the following url http://yourdomain.com/system/index.php?/cp/addons/settings/wyvern/uninstall[?s=......] this wil uninstall only the addon tables and does not remove or change any of your entries.
  2. After you uninstall the module, you will be automatically return to the Addons overview page. From here, install Wyvern as you did with any module in EE
  3. Fill your license in the settings page to activate the Module
  4. Open your custom fieldtypes and resave every Wyvern field so the settings will be applied with the new format.

If this does not work, you can contact us via http://addons.reinos.nl/support
