Installed Plugin Page is redirecting

That screenshot looks like a JetPack dashboard page to me instead of a ‘404’ page.

Maybe you might start by disabling Jetpack by renaming that Jetpack directory under the plugins directory via ftp or your control panel’s file manager… just add 1234 to the directory name to kill any single plugin temporarily.

Rename the whole plugins directory to kill them all.

it’s just a screenshot sample.

The issue is that when I click on Installed Plugin it redirects me to tho mydomain/404

and when I click on add new plugin so that link is fine. I can add new plugin & then it redirects ,e to the plugin redirectory where all plugins are installed.

but just if click on installed plugin it redirects to 404

You might need to reinstall WordPress. If you run your cPanel or use an FTP client and go to the wp-admin folder, do you see a plugins.php file?

Yes Pligins.php File is Present Sir.

And is the Installed Plugins menu pointing to it? Right-click on the Installed Plugins menu item and select Copy link address from the pop-up menu and paste it into a text editor. Confirm that it’s pointing to your mydomain/wp-admin/plugins.php file.
