Problem: The client reported significant slowdowns on their staging site after installing WPML, with page load times increasing to 6-10 seconds. This issue was not present on a similarly configured site without WPML. The client tried various optimizations, including disabling WPML SEO and WPML String Translation modules, which improved load times.
Solution: We recommended migrating the site to our Cloudways testing environment to isolate the problem. The client used the Cloudways WordPress Migrator plugin for this purpose. After migration, we discovered that the combination of Admin Columns Pro, ACF, and ACFML plugins significantly impacted performance. We provided a temporary workaround by modifying the
translateField
method in the ACFML plugin to prevent certain processes from executing in the admin area, which improved backend performance. We also advised on general performance enhancements such as using PHP 8, enabling caching, and optimizing database indexes.

Problem: The client is experiencing a deprecated warning with
Deprecated: str_contains(): Passing null to parameter #1 ($haystack) of type string is deprecated
when using WPML with PHP 8.2. The issue seems related to a compatibility problem between LearnDash and WPML. Solution: We recommend reproducing the issue on a clean staging site with only WPML and LearnDash LMS activated. If the issue persists, follow these steps: 1. Backup your site. 2. Switch to a default WordPress theme temporarily. 3. Deactivate all unrelated plugins. 4. Check if the issue still exists. 5. Reactivate plugins in groups to identify the problematic one. 6. Switch back to your original theme. If you identify the plugin causing the issue, you can apply a temporary patch provided by the client. Additionally, our developers are aware of this issue with PHP 8.2 and are working on a fix expected in WPML version 4.7. Meanwhile, to avoid displaying errors to site visitors, disable debug mode by adding
define('WP_DEBUG_DISPLAY', false);
to your wp-config.php file. For more details on related issues, please visit this errata page.

Problem: You are experiencing a styling issue in the backend when using the Gravity Forms Multilingual addon, resulting in a broken UI. Solution: We recommend disabling the No Conflict mode in your Gravity Forms settings. This mode, when enabled, prevents third-party scripts from affecting the Gravity Forms administration pages, which can lead to styling conflicts. To disable it, edit your form settings and turn off the No Conflict mode. For more detailed instructions, visit the Gravity Forms documentation: https://docs.gravityforms.com/enabling-no-conflict-mode/

Additionally, we suggested disabling the 'Keep repeater and flexible sub-fields in the same order as the default language' option and then updating the post.
We also informed the client that a new version of ACFML (2.1.2) has been released, which includes a fix for this bug. We advised upgrading to the latest version after a full site backup: ACFML Changelog.
