"Add link" is not working (after submit -nothing happens)

[sasu]

Hello, I noticed that "Add link" is not functioning.
Paint a word, click "add link" (choose any link type..) and submit, nothing happens. There are no error messages.

The link (same for email, resource) is added but without any content, check HTML source.

I'm not sure where to look, is it refinerycms-wymeditor, refinerycms-core or refinerycms-pages?
