Problem:
The client reported a compatibility issue between the WPML SEO plugin and PHP 8, causing problems on their website. The hosting provider had temporarily switched back to PHP 7.4, but the client needed a solution to use PHP 8.
Solution:
1. We requested temporary access to the site to investigate further, including wp-admin and FTP details, ensuring the client backed up their site first.
2. We suggested increasing the WP Memory Limit to 500M, providing a guide on how to do this: guide.
3. We asked the hosting provider to share any error logs related to the WPML SEO issue and to upgrade PHP to 8 on the staging site for further testing.
4. We resolved an issue with missing pages/posts when WPML was activated by running WPML troubleshooting actions and assigning the correct language, which made all pages visible again.
