Admin/Edit Page Not Displaying Correctly

I’m in the process of transferring from wordpress.com to ww.wp.xz.cn. A couple weeks ago I had trouble with my admin page not rendering correctly (looked similar to the screenshot below), but I was able to fix it by deleting some plug ins. Unfortunately, I went to edit some pages and found the page editor was not displaying properly either. Here is a screenshot:

I’ve tried a couple of different things that I’ve seen around these forums and other websites. Most notably being extending the storage to 256m; adding this to my wp-config.php:
define( ‘CONCATENATE_SCRIPTS’, false );
define( ‘SCRIPT_DEBUG’, true );

And adding this to my loading-styles.php:
error_reporting( E_ALL | E_STRICT );

If anyone could help that would be great because I’m hoping to have my site live again in the next 2-3 weeks to correspond with an upcoming marketing campaign. Literally all I have left to do is upload some images and make minor changes.

Thanks!
