Apa SEO

Problem:
You registered your site with a sitekey but encountered an 'ATE Error' and received a 'No sitekey found for this website' authentication error, which prevents you from translating articles. The issue was identified to be caused by the bbPress Notify plugin, which, when deactivated, resolved the translation workflow issue.
Solution:
We have confirmed that the bbPress Notify plugin is currently not listed as WPML-compatible. To resolve this issue, we recommend contacting the plugin's author directly to inquire about adding or improving WPML compatibility. You can reach out to them via their support forum at https://wordpress.org/support/plugin/bbpress-notify-nospam/.

If this solution does not apply to your case, or if it becomes outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should you need further assistance, please do not hesitate to open a new support ticket at WPML support forum.
