Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-related problems?
That doesn’t seem to help.
To explain further, text shows up when I highlight it, but not otherwise. And I can’t switch from HTML to Visual.
It’s a well-known problem that is normally caused by an incompatible plugin.

I’m a bit of a techno-dummy… can you please explain this suggestion to me:
Add define( ‘CONCATENATE_SCRIPTS’, false ); near the top of wp-config.php. That would make WordPress admin run slower, so can try removing it in a few days and testing again (this would eliminate any stale network cache)
What do I need to do here?
Download your wp-config.php file from the root folder of your WordPress site to your own machine. Open it in a plain text editor (eg NotePad – not Word or any other word-processing application) and, immediately after,
* @package WordPress
*/
press Enter once, add the line suggested above then press Enter again. Save the file and re-upload it to your site.
