  Hi everyone, yesterday unexpectedly after doing a site health check and enable wp debug my domain reported an HTTP 500 error, I no longer have a way to access the back-end and much less the front-end, I can’t get to the bottom of it. Let me start by saying that I tried to disable all the plugins, change to the default theme and reinstall the wp core but without success, I attach the error log of my server so that you can have a complete picture of the errors, thanks for the help

  Hi there,
  
  Unfortunately, we cannot assist because ricreo.shop is not on WordPress.com but is a self-hosted WordPress.org site hosted with Namecheap.

  To clarify:

  • WordPress.com is a managed host platform that offers WordPress in a pre-customized server environment already set up for you to build your site. Hosting with WordPress.com is free, and the server, security, updates, and site optimization are all handled by us. We offer free and paid plans that provide additional features for your site based on your needs (plugins, custom themes, etc). You also have access to professional assistance via Happiness Engineers to address any issues you encounter.
  • WordPress.org is a self-hosted platform, meaning you download the WordPress software and install it on a web server from a host of your choosing (Go Daddy, Bluehost, Hostgator, etc.). You have to pay the host when you’re self-hosting, and the server, security, updates, and site optimization are all handled by you. This gives you more flexibility and control of your plugins, themes, and code, but also more responsibility to ensure those things are operating correctly.

  Our support page dives more into the differences:
  
  https://en.support.wordpress.com/com-vs-org/

  Here is information on addressing the HTTP 500 error you are receiving:

  https://www.wpbeginner.com/wp-tutorials/how-to-fix-the-internal-server-error-in-wordpress/
  
  We welcome you to consider moving your site to WordPress.com, as we’d love to further help you. However, since you’re on a self-hosted platform, we do not have direct access to your account and therefore can’t directly address your issue.

  I recommend contacting Namecheap, as they would be better positioned to assist you since they have access to your account. Also, the open-source forum community is always available and prepared to help users with self-hosted sites:

  Thanks!
