Problem: You are experiencing a fatal error when trying to edit or add a translation in WPML, despite having updated PHP and WP memory limits and contacting your hosting provider to address issues in the wp-option table. Solution: First, ensure that your user profile under Users-> Profile includes an email and a nickname, and make sure to update this information. Next, navigate to WPML-> Translation Management -> Translators tab and verify that your profile is listed as a translator with the correct language pairs.
If this solution does not resolve your issue or seems outdated, we recommend checking for related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 problems persist, please open a new support ticket at WPML support forum for further assistance.
