[...] Some head scratching, googling and making a support request to Dreamhost followed. Apparently they had just had an outtake, so thought it was related. They did too. But it was not! I finally found the answer on a blog: Turns out this error is not alone in WordPress and not a bug of it at all. Some of the administration tasks of other CMS software such as posting posts with PHP code in them and uploading stuff would also trigger a module in Apache called Mod_security to be over sensitive. — http://www.kavoir.com [...]

Anywhere would do, just insert them in the .htaccess at the root of your site.

hI, Yang!

Great post, buddy! Just little stuck somewhere.. As I am newbie, I don’t know much about networking and apache.

I am getting this error, while I try to access my dashboard. It says: “503 Service Unavailable”. But it’s let me log in, I mean I can see /wp-admin page. But While it tries to go Dashboard it gives the error.

I don’t know where to put the code, Would you please explain me where should I put it in .htaccess. I hope I made my point clear.

Thanks in advance.

Actually it turns out that it’s caused by Mod_security an apache security module.

Same thing for me – PHP’s curl_exec() triggers “Service Temporarily Unavailable”. Is it a bug or a security measure trying to squash exec()?

I might try modifying the file via FTP. But then I probably wont be able to edit it the normal way anymore.

For me it was curl_exec() that triggered this error.
