Let’s make sure all the files are there. From UPDATES on the dashboard, click the button to reinstall the current version of WordPress. See https://i.imgur.com/eIM57q0.png

Hello, I just reinstalled WordPress. I am still getting the same error message when I click Plugins.
In your dashboard, what link do you see for “plugins”?
What is the link when you hover over it?
How are you hosting your site?
I am nit sure what you are asking.
When I hover over Plugins, I see “Install Plugins”, “Add New”, “Plugin Editor”
Acenet is the hosting company.
Right click on plugins. Select “copy link”. Paste it here.
Are there any errors in the log files?
OK, that’s the right link.
If you look in wp-admin (via FTP or your hosting control panel’s file manager app) is that file (plugins.php) there?
Am I looking in the root directory?
in the wp-admin directory
What’s in your .htaccess file? Please copy/paste here. Also, please check the server’s error log(s).
