A 500 error could be caused by a number of different things. Have you tried to temporarily deactivate all plugins (apart from the AMP plugin) temporarily to see if there is a plugin incompatibility?
Hello I have the sudhir600’s same problem. The only thing I did is to rebuilt my VPS to ubuntu 18.04 LTS. All the sites in this new VPS have the same ERROR 500. Please help. https://tambopata.com.pe/eco-magico-3-dias-2-noches/?amp=1
Thank you.

I have deactivate all plugin and the error still continue.
Did you try the following release candidate version? Give it a try, but before installing delete your existing plugin first. I can’t say it will fix it, but try after deactivating your SEO and Gravity Forms plugin.
It could be a .htaccess file issue also with your new hosting setup. But try the above first.
If there is a 500 error, please look at your server logs to identify what the error is.
Thank you for your help. I enable debug in wordpress and I saw the following errors:
Fatal error: Uncaught Error: Class ‘DOMDocument’ not found in tambopata.com.pe/public_html/wp-content/plugins/amp/includes/utils/class-amp-dom-utils.php:65 Stack trace: #0 tambopata.com.pe/public_html/wp-content/plugins/amp/includes/utils/class-amp-dom-utils.php(324): AMP_DOM_Utils::get_dom(‘<html><head><me…’) #1 tambopata.com.pe/public_html/wp-content/plugins/amp/includes/templates/class-amp-content-sanitizer.php(27): AMP_DOM_Utils::get_dom_from_content(‘<div class=”ui …’) #2 tambopata.com.pe/public_html/wp-content/plugins/amp/includes/templates/class-amp-content.php(185): AMP_Content_Sanitizer::sanitize(‘<div class=”ui …’, Array, Array) #3 ambopata.com.pe/public_html/wp-content/plugins/amp/includes/templates/class-amp-content.php(118): AMP_Content->sanitize(‘<div class=”ui …’) #4 tambopata.com.pe/public_html/wp-content/plugins/amp/includes/templates/class-amp-content.php(76): AMP_Content->transform() #5 tambopata.com.pe/p in /home/ramiro/tambopata.com.pe/public_html/wp-content/plugins/amp/includes/utils/class-amp-dom-utils.php on line 65
Any Idea?
thank you very much.
I just needed to install: sudo apt-get install php-dom , now everything`s fine.
thank you very much.
Congrats @ramiro100 for solving this issue. but i have few question
1. what is the apt-get install php-dom and
2. how to install the same for linux share hosting (i have no sudo access)
Finally I got success. Thanks ramiro for your research.
Those who are using linux shared hosting and have no access of sudo then follow this step.
1. login to cpanel
2. search “php version” or just php
3. click on “select php version”
4. choose php 7.1 or upper version then find “DOM” in that page. (that will be one from from module list)
5. check that and save.
6. come to wordpress and clear the cache..
“Thats it.. now your page will work like this -” https://comedymood.com/adventure-places-india/amp/
Aside: v1.1 of the plugin will show an admin notice when the DOM extension is not present. See https://github.com/Automattic/amp-wp/pull/1533
