Hi,
We are component developers, not template developers.
Our support is for components, we do not provide support for products that we don't developed.
You can replace the line with
In order to hide the error, or just delete the line. We do not have any knowledge for that so the best is to contact the template developer and wait for their answer.
Best we can't help you for that.
For the rest, you can see our answer from the "contact us" page.
And please, do not duplicate messages using the forum and the "contact us".
Please understand that we can't reply in the minute and that during the week end, the delay is higher.
Regards,
