 * Hi,
 * first – send a message and after the error shows send another message: [debug].
   A red rectangular will show (below) with more detailed message error. I would
   need to know this message in order to find what is wrong.
 * Thanks

 * I can debug this only if you share a link to your website. The errors you pasted
   here are not enough unfortunately.
 * Thanks
