Solved!!!
Once the wp-config file is set correct as above,
1. delete all plugins
2. reinstall your theme
3. Check your site, sit back and feel sweet victory 🙂
So ive managed to bring the editor back by:-
1. find the file & edit wp-config.php .
2. On wp-config file, line 87, set this define(‘DISALLOW_FILE_EDIT’, true);
3. set to false
im completely lost …. completely reinstalled wordpress again and still have the same problem
does anyone have any ideas?
