Please take a look of my website I tried to change text or image on slider but doesn’t work. Wrote me please how to do it. I will give you access in private
We see 503 error when trying to open Slider revolution in your dashboard. 500 Internal Error is a generic error and says about some issue on the server and can be caused by different things. Anyway, to understand its nature you need to see your server error logs or enable PHP error display on the website. If you can’t do this, you need to contact your hosting provider for help in this question. Here is an article that may help you understand the error better http://www.wpbeginner.com/wp-tutorials/how-to-fix-the-internal-server-error-in-wordpress/
