Shows raw data instead of tree

I’m using CMSTW 0.7.19 over WP 3.1.3 Multisite.

It’s a very specific issue, it happens only in one of my sites and only with a specific custom post type: instead of showing the tree, it shows raw data like this:

[ { "data": { "title": "Post title", "attr": { "href": "https://example.com/wp-admin/post.php?post=1&action=edit", "xid": "cms-tpv-1" }, "xicon": "https://example.com/wp-content/plugins/cms-tree-page-view/images/page_white_text.png" }, "attr": { "xhref": "https://example.com/wp-admin/post.php?post=1&action=edit", "id": "cms-tpv-1", "xtitle": "Click to edit. Drag to move.", "class": "cms_tpv_user_can_edit_page_yes" }, "metadata": { "id": "cms-tpv-1", "post_id": "1", "post_type": "mycustomposttype", "post_status": "publish", "rel": "publish", "childCount": 0, "permalink": "https://example.com/mycustomposttype/post-title/", "editlink": "https://example.com/wp-admin/post.php?post=1&action=edit", "modified_time": "24/05/2011", "modified_author": "John Doe", "columns": "", "user_can_edit_page": "1" } }

Seems to me that it never finishes loading all available content. This particular CPT has 500+ entries, maybe that’s the issue.

Let me know if you need any further information that I can provide.

Thanks,

Ricardo
