After upgrading some files manually from 220.127.116.11 to 18.104.22.168, the content of my WYSIWYG in CMS pages is not showing in the frontend. Everything else works fine (admin, other pages, catalog and even the other content of the CMS page). If I have a CMS page with html inside the WYSIWYG and a block defined in the XML layout (product list, for example), the product list will show, but the content of the WYSIWYG will not.
There are no errors in the page (even enabling developer mode and display_errors) and the content is not hidden by css, it is not there at all. Looks like the script responsible for CMS pages is not outputting the WYSIWYG content.
