Problem:
If you're experiencing blank or white pages on product pages using WoodMart custom layouts when WPML is active, and this only occurs with products having many variations (10-15+), while products with fewer variations display correctly, we can help.
Solution:
We recommend updating a specific function in your WPML plugin files. Please locate the file

sitepress-multilingual-cms/addons/wpml-page-builders/classes/Integrations/Elementor/class-wpml-elementor-adjust-global-widget-id.php

and modify the function

duplicate_css_class_with_original_id

around line 132 to the following:

public function duplicate_css_class_with_original_id( $content ) {<br />    $classPrefixes = implode( '|', [ 'elementor-', 'elementor-global-' ] );<br />    $pattern       = '/(class="[^"]*?((?:' . $classPrefixes . ')))(\d+)/';<br />    $result        = preg_replace_callback( $pattern, [ $this, 'convert_id_to_original' ], $content );<br /><br />    if ( null === $result ) {<br />        return $content;<br />    }<br /><br />    return $result;<br />}

After applying this change, please clear any caches on your site to see if the issue resolves. This modification addresses template display failures due to the PHP setting

pcre.backtrack_limit

being exhausted. A permanent fix is anticipated in WPML 4.9.

If this solution does not apply to your case, or if it becomes outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. Should you need further assistance, please open a new support ticket at WPML support forum.
