Since TinyMCE is the editor, that’s pretty much the problem. Let’s start by trying to reinstall it. From the Dashboard, select “updates” then “reinstall wordpress”. Maybe it’s just a missing file.

I now have wordpress 9 site is still good but I still cannot type or see my posts.

This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.

If you can install plugins, install “Health Check”: https://www.ads-software.com/plugins/health-check/ On the troubleshooting tab, you can click the button to disable all plugins for you, while you’re still logged in, without affecting normal visitors to your site.

All plug in deactivated and theme 2017 installed. It hasn’t made any difference.

Try adding this to wp-config.php

define( 'CONCATENATE_SCRIPTS', false );

put it at the top, below the first <?php

Sorry no idea how!

Using FTP or your hosting control panel’s file manager app, download wp-config.php. Edit the file, and then re-upload.

I have searched for this file in cpanel and it comes back data error. Sorry if I am being stupid I would like to understand this but finding it difficult.

It’s in your public_home directory.
