My website is not longer accessible due to internal server error.

If i change theme everything goes back to normal so it's a theme issue, is the second ticket i have to open because no one answer me! 

Can you please check what's wrong and help me? That would be of help! 

If anyone had the same problem and solved it please show up!

Thanks again.

Hi Michael,

It shows problems just if i navigate https://www.bridgemediasolution.com/wp-admin/

And the strange thing is that when i use my wifi it goes well but any other colleagues or me without using wifi get the error.

but this doesn't happen when i change theme
