Problem: You are experiencing a critical error after installing and activating the Sticky Links plugin while trying to edit a page. This occurs when WPML is installed but not fully configured. Solution: We recommend completing the WPML configuration before installing the Sticky Links plugin. This should serve as a workaround to prevent the critical error. If this solution does not resolve your issue or seems outdated, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. If further assistance is needed, we encourage you to open a new support ticket at WPML support forum.
