[Resolved] Advanced Translation Editor enabled and activated but still getting error

Thank you for contacting WPML support. I'll be happy to help you with this.

Could you try the following?

- Backup your site's Database
- Go to WPML > Setting and enable the "classic translation editor"
- run this query in your site's database:

select *
from wp_options
where option_name = 'WPML_SITE_ID:ate'
OR option_name = 'WPML_TM_AMS'
OR option_name = 'otgs_wpml_tm_ate_cloned_site_lock'

-------------------
Note: "wp_" is the prefix of your WP installation, so you might have to change it to suit yours.

Note 2:
If you don't know how to run this query, you can also search for the following entries in the wp_options table of your installation

+ otgs_wpml_tm_ate_cloned_site_lock
+ WPML_TM_AMS
+ WPML_SITE_ID:ate

-------------------

- Delete those entries
- Go to WPML > Settings and re-enable ATE
- Flush the site's cache if present

Before proceeding with any changes, please make sure to back up your database first.
