BuddyPress – PHP Fatal Error: Uncaught ArgumentCountError: Too Few Arguments to Function WPML\\BuddyPress\\Groups::translateExcerpt()

Overview of the Issue

A recent update to BuddyPress 12.4.1 has introduced a compatibility issue with WPML, specifically concerning the handling of group descriptions. This change has led to a fatal error when the BuddyPress filter bp_get_group_description_excerpt is called, as it now lacks a necessary second argument that was previously expected:

[06-May-2024 15:51:02 UTC] PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function WPML\\BuddyPress\\Groups::translateExcerpt(), 1 passed in ..../wp-includes/class-wp-hook.php on line 324 and exactly 2 expected in .../wp-content/plugins/buddypress-multilingual/includes/class.groups.php:84

This issue has been already reported (opens in a new tab) to BuddyPress team.

Workaround

Please, make sure of having a full site backup of your site before proceeding.

• Open …/wp-content/plugins/buddypress-multilingual/includes/class.groups.php file.
• Look for line 84.
• Replace:

  public function translateExcerpt( $excerpt, $group ) {
  	$getTranslation = $this->translate( 'description' );
  
  	return bp_create_excerpt( $getTranslation( $excerpt, $group ), strlen( $excerpt ) );
  }

• With:

  public function translateExcerpt( $excerpt, $group = null ) {
  	if( is_null($group ) ){
  			return $excerpt;
  	}
  
  	$getTranslation = $this->translate( 'description' );
  
  	return bp_create_excerpt( $getTranslation( $excerpt, $group ), strlen( $excerpt ) );
  }
