You need to roll one upgrade one by one.

Hello,
I can help you with this. I want to know did you update the WordPress or updated the plugin?

Roll back everything before you made an update.

Internal Server Error Messages are corrupt .htaccess files, file permission errors, timeout scripts, inappropriate PHP versions, or due to WordPress updates. However, there are many other errors. So you need to dig deeper to find out the exact cause of the error. One of the best ways to troubleshoot WordPress Internal Server Error is to review your old steps. Remember exactly what caused the site to stop working (for example, when updating the plugin / theme). As you know, solving problems will be much easier.

Look at your webHosting Server, hope it helps yeah

Did you check file permission? Maybe your web server doesn't have access to some file.

All permissions were. We have long suffered to solve the problem. And I decided to just move the site to WordPress

An "Internal Server Error" often occurs due to:

1. Misconfigured Drupal core file or folder read and write permissions.
2. Misconfigured web server file or folder read and write permissions.
3. Corrupted files.

Can you send a screenshot of the error report..??
It can be because you did not install the update properly.
