I've updated assets from an ancient 1.* version to latest 3* and everything looked ok apart when I've tried to edit a page. I'm getting the following error: Fatal error: Call to undefined method Assets_ft::content_id() in system/expressionengine/third_party/assets/ft.assets.php on line 2467
For many reasons I can't update at the time being the EE 2.5.5 which is currently installed.
Anyone with a suggestion?
