WordPress Admin Dashboard Does Not Display Correctly

Seems a duplicate. https://stackoverflow.com/questions/11916987/uncaught-syntaxerror-unexpected-token-illegal-load-scripts-php1, Try to find that error with Google as there are a lot of results

You can also try editing your wp-config.php file ( it is located on the root folder of your installation ) and right before the lines that say:

/* That's all, stop editing! Happy blogging. */

and add this

define('CONCATENATE_SCRIPTS', false);

This will tell WordPress to load each script on it’s own instead of combining them. This might be caused due to some faulty or outdated plugin .js that overrides something else when it is concatenated.

If that doesn’t fix your problem, try to deactivate all plugins moving them to a temp folder via FTP or renaming the plugins folder to sth like plugins_old. Maybe one of them is causing the issue here…
