I am trying to: upgrade from 4.3.16 to 4.3.18

Link to a page where the issue can be seen: the upgrade process fails and falls back to the last known good state

I expected to see: a successful upgrade

Instead, I got:

Thank you for contacting WPML support.

The error you mentioned comes from 'WordPress SEO Premium' not from WPML.
Please disable or delete that plugin and try to update again. It should work then.

Let me know the results, please.

The update fails on the following 3 plugins:
- WPML Media
- WPML Multilingual CMS
- WPML String Translation

The stack trace I sent is from one of the upgrades, which is why it does not necessarily match up. It doesn't change the fact that none of the upgrades works.

Please help!

In this case, please try to update these plugins manually.
This will fix the issue.
