WPForms Form Pages - 404 Error on Secondary Language Form Pages

Overview of the issue

If you are using WPForms and its WPForms Form Pages addon, you may encounter a 404 error when accessing form pages in secondary languages with a custom permalink structure (e.g., /artikel/%postname%/).

Workaround

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

• Open …/wp-content/plugins/wpforms-form-pages/src/Frontend.php file.
• Look for line 78.
• Replace:

  			$request = ! empty( $request ) ? sanitize_key( wp_parse_url( $request, PHP_URL_PATH ) ) : '';
  

• With:

  			if ( ! empty( $request ) ) {
  				// Parse the URL to get the path component
  				$path = wp_parse_url( $request, PHP_URL_PATH );
  		
  				// Use a regular expression to remove the language segment (e.g., "/en/") from the path
  				// This pattern assumes the language code is always two characters and follows the first "/"
  				$path = preg_replace( '#^/([a-zA-Z]{2})/#', '/', $path );
  		
  				// Sanitize the resulting path
  				$request = sanitize_key( $path );
  			} else {
  				$request = '';
  			}
