 * Hi there,
 * I recently update the Page Builder by Site Origin plugin to v2.31.8, and then
   the Page Builder by Site Origin plugin shows the following warning message:
 * Warning: Undefined array key “sync” in …/wp-content/plugins/siteorigin-panels/
   compat/polylang.php on line 45
 * It was just fine with the previous version, so I rollback to v2.31.7 .
 * Please kindly troubleshoot this issue.
 * Thank you.
