This thread is resolved. Here is a description of the problem and solution.
Problem:
The client reported significant slow performance with the WPML plugin activated, particularly when the String Translation plugin is enabled. The issue persisted despite switching themes and disabling third-party plugins. Profiling indicated that the slowdown was related to the ACF Multilingual plugin, specifically with the handling of WYSIWYG fields in custom post types (CPTs).
Solution:
We identified a specific code snippet causing the issue in the ACF Multilingual plugin. We recommended modifying the code in the
ACFML\Field\FrontendHooks::convertTargetLinks
file. The client should locate the line:
if ( $isWysiwygField && is_string( $value ) ) {and change it to:
if ( $isWysiwygField && is_string( $value ) && strpos($value, 'http') !== false ) {This change prevents unnecessary processing unless the field contains a link, which should mitigate the performance issue. We are also working on a more permanent solution to be included in future WPML releases.
If this solution does not resolve your issue, or if it seems outdated, we recommend opening a new support ticket. Additionally, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
