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:

  1	$request = ! empty( $request ) ? sanitize_key( wp_parse_url( $request, PHP_URL_PATH ) ) : '';

• With:

  1 2 3 4 5 6 7 8 9 10 11 12 13

  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 = ''; }
