Tags not saved on Posts/CPT

Hi,

No it fails on standard posts as well. It might save some keywords but not all (refer to example in previous post).

> Just to make sure. You add tags using the “tags” metabox on the right side when editing a post.
Yes, I’m using tags metabox – a complete standard wordpress widget for posts/CPT.

> Do the tags appear in the list and then disappear when you save the post?
Yes you can see all of them when added, but once you click publish or update some of them simply disappear. I think it might be that the ones not available in drop down/autocomplete list are not added as expected.

Does it happen when creating new tags or when choosing existing ones or both?
> Looks like when choosing existing tags though there is ~2k tags so I can guarantee 100% that it affects all.

Is always only the last one saved ? Or did you experiment different situations?
> The order don’t really matter, its just some of them are not saved. I could add it as first or as last its has something to do with tag or some of its properties (languages meta data?)

Could you make tests with only Twenty Twelve and Polylang activated? If it does work, could you check if the conflict is coming from your theme or another plugin?
>Activated Twenty Twelve and the problem persists. There is no other plugins activated just Polylang and once deactivated it allows to save those tags I mentioned in first post.

Seems to be working great! One more question, will these change will be include in the upcoming releases or I should lock plugin to this development version to avoid any problems in future?

Ok. Thanks!
