Problem:
After restoring a backup, the following error appears:
Fatal error: Uncaught Error: Interface 'WPML_Log' not found in /home/photopuzzle/public_html/wp-content/plugins/sitepress-multilingual-cms/classes/xml-config/class-wpml-config-update-log.php:6
Solution:
This is probably happening due to some missing/corrupted files after the backup restore. Please try the following:
1. Delete the "sitepress-multilingual-cms" plugin folder from the plugins directory
2. Go to the WP dashboard and deactivate the other WPML plugins
3. Download a new version of the "WPML Multilingual CMS" plugin from https://wpml.org/account/downloads/
4. Extract and upload it to the plugins folder
5. Activate it
