1. Please take a backup of your site first for security reasons.
2. I have noticed that your website’s WP Memory Limit is 40MB.
The WP memory limit needs to be increased, it's different from php memory.
PHP memory is fine but WordPress uses 40Mb as default in your site. Minimum requirements for WPML are 128Mb: https://wpml.org/home/minimum-requirements/
Please add this to the top of wp-config.php to increase WP memory:
3. Please go to WPML >> Support >> Troubleshooting page and press below buttons:
- Clear the cache in WPML
- Synchronize posts taxonomies
- Remove ghost entries from the translation tables
- Assign translation status to duplicated content
- Fix post type assignment for translations
- Set language information
4. Please delete all sorts of caches on your site / server cache if any / plugin cache (LiteSpeed Cache) / CDN cache (if any), clear browser cache and then see if it resolves the issue afterwards.
