Thank you for getting in touch with us. My name is Attila and I'm happy to assist you today. I appreciate your patience while we've been working towards your ticket.
The "Internal server error" is a web server configuration issue. In your case it could be a memory limitation problem or execution time limit, because you are trying to utilize more content than your server can handle in the given amount of time. But it might be generated by something else as well.The "Internal server error" is almost always a PHP error related problem, but currenty the exact error message is not visible as the WP debug mode is not enabled. Please try to enable it and look for any PHP errors in the logs that could provide more information. https://codex.wordpress.org/WP_DEBUGhttps://codex.wordpress.org/Debugging_in_WordPressIf you're not familiar with it, your host should be able to help you locate it and fix the problem on their end.In the meantime please also try to look for any incompatibility problems by temporary disabling other plugins and switching to a default theme. Just to make sure that it's not caused by a 3rd party item.
Regarding the sliders not appearing. I've checked the URL you provided, but there is no LayerSlider added to that page currently. Please show us where the slider is inserted so we can check on it.
