Hi, I'm Alan, 

I just noticed that there is the "error 500" appearing on some of your website pages. I'm pretty positive that those types of errors won't be appreciated by your customers and you are basically losing money as a result, plus they can significantly reduce the number of clicks from Google. 

I've decided to help and created the document for you with a few screenshots of errors and also indicated the links to the pages where they appear, hope it helps. 

Here's the link to the doc, check it out:

Have a good day!
