EZ-Page does not appear in header & footer

Hello, after an update of EZ-pages language package our zencart does not work. When I change EZ-page name (two language) nothing appears in the header and footer. There is no error message... we also tried the fix it but it does not show nothing on header&footer. Does anyone know how to do? thank you very much

By "ez-page language package" do you mean the Multi-Language EZ-Pages mod? If so, that has some customized files to display the different language links in header, footer and sidebox; it sounds like you are missing some of those. Seeing the site live may help diagnose the issue. First check the files in the mod package against the versions in your custom folders on the server and make sure they are all in the right places. (If they were corrupted you would be seeing PHP errors instead of just no content.)

What exactly did you do to try to fix it?
