Problem:
You are trying to complete a translation using the Advanced Translation Editor, but the displayed completion status is stuck at 99% even though all fields are translated.
Solution:
We recommend contacting your hosting provider and requesting them to increase the

max_input_vars

value to 10000. You can verify the current

max_input_vars

value in WPML -> Support. After making this change, please double-check if the issue has been resolved.

If this solution does not apply because it might be outdated or not relevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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. If the problem persists, please open a new support ticket at WPML support forum.
