Having the same problem here..
I Also tried:
- define(‘CONCATENATE_SCRIPTS’, false); in wp-config.php
- reinstalling wp 3.5.2 update
- reuploading wp-admin images
- clearing browser cache/cookies
What theme are you using?
Which plugins are you using?
Did your problems also apear after after WP 3.5.2 update?
Maybe we can put our heads together and sort it out..
Hi, are you guys using a mac, maybe? I had the same problem and my visual editor was only working on a PC running windows. yes, it is strange.
I tried all of this:
– define(‘CONCATENATE_SCRIPTS’, false); in wp-config.php
– reinstalling wp 3.5.2 update
– reuploading wp-admin images
– clearing browser cache/cookies
– deleting all the plugins and activating the twenty eleven theme
And yes, this issue appeared after the 3.5.2 update.
Yep!
I’m on a Macbook Pro running OS X Lion (10.7.5), problem was there on both latest Chrome and Safari. Also just booted into Snow Leopard (10.6.X) and tried on that partition with no luck.
Which OS X were you using?
I Don’t have a PC with me – deleted my bootcamp partition a couple weeks ago of course. However, just logged into WP admin via Chrome on my iPad, loaded up the visual editor and everything’s there.. So you’re right, looks like it might be an OS X thing.
Oh well, wait for a patch I guess?
Got it.
I’m on a Macbook Pro running OS X Mountain Lion. The problem was on latest Safari and Chrome too. I tried to install a Windows 7 on my Parallels app and tested on latest IE/Chrome/Firefox with no luck.
I almost out of ideas.
Very unlikely that it’s OS-related. Have you tried deactivating all plugins and switching to the twentytwelve theme? Also be sure you’ve cleared any cache and cookies on your computer and site.
Also, this thread is about 502 Bad Gateway errors – which are server-related – so each of you except the OP really should be starting a new thread per

Ty, Yogi, i’ll start a new thread.
Hi guys,
Apologies for the late reply, but I’ve finally managed to fix mine! I’m on a mac also but that wasn’t an issue. Turns out it was the BulletProof Security plugin that had somehow managed to bork everything.
After deleting all traces of the plugin from my WordPress install and server, deactivating all other plugins, re-installing WordPress and reactivating my plugins – success!
If you don’t have the BulletProof Security plug in I’m out of other ideas, otherwise delete all traces of it (dont’ just deactivate it) and see how you go.
502 errors typically indicate a communication/connectivity problem. See the link below.

Since BPS was mentioned here I will only list the most likely possibility that could be directly related to BPS – .htaccess files are not supported or compatible with you particular Server Type or configuration. Example: nginx frontend Server that is not using Apache on the backend to process php.

There was a problem with older versions of BPS blocking square brackets [ and ] in WP 3.5, which caused the WP visual editor to not function correctly. This was corrected within hours by releasing a new version of BPS.
There are a few plugins that add .htaccess code to your root .htaccess file that are still blocking square brackets and the 5G Blacklist does this as well so it is possible that your root .htaccess file contained this type of code and by deleting your root .htaccess file that fixed the problem.
