Shouldn’t be. Ask your host to get you your server’s PHP Error log. It’ll be full up of stuff, if you’re getting 500s.
Then, post that here, and we’ll help identify where the errors coming from.
I have verified my site and the error logs do not reflect any issues. The last error is yesterday and has nothing to do with this.
The two most common causes of this error are a corrupted .htaccess file and exceeding your server’s PHP memory limit.
The .htaccess file in your WordPress directory can become corrupted after you install a plugin or make another change to your WordPress site. All you need to do is create a new .htaccess file.
The .htaccess file is the same, I have reviewed it and it has not been modified.
Topic solved. The problem was in an RTMedia plugin, which was outdated. Once updated this plugin, the rest has been left to install to perfection. Thanks to all for the help
Thank you @tempsgranollers for the feedback.
It is always important to update WordPress to his latest version.
This rule is also valid for plugins and themes
