I've installed Zen-cart 1.3.8 and the Multi-Language Support for EZ-Pages module.
I had the same problem as above; on some ez-pages (not all) I had double breadcrumbs. I commented out the $breadcrumb-line as described by oculas and now it works fine.

But I still have a problem:
I have an ez-page link in the important information box to a content page wich works fine.
Another ez-page link in the footer with an internal link to the site map also works fine.
BUT the ez-page link in the footer to a content page doesn't work. It shows the link and title but the content on the webpage shows the word array. Although in the table the right content is inserted.

Does any one have a clue??
