Save button missing from content type edit form Here is what the bottom of my "leaflet" content type edit form (i.e. admin > structure > content types > leaflet > edit) looks like:


Here is what the bottom of my "testimony" content type edit form looks like:


Note that there are no save/delete buttons! Another of my content types has also now picked up this bug. This just happened. I have no idea why. I can't save changes! I tried flushing all caches and it didn't help. I'm an administrator and I have permissions for everything.

Why would this have happened and what can I do? Drupal 7.19.
The problem was the i18n synchronize translations module. Disabling it fixed the problem. Of I have to immediately re-enable it afterwards since I actually use this module. So I filed an issue: http://drupal.org/node/2004260. Thanks to Ayesh K who gave me the idea in his comment on my question. Since it's not an answer I can't mark it correct, so I'm just answering here and will mark this correct.
