HTTP Apache – 503 Error – Service Unavailable

503-errorapache-2.2

I have installed Drupal 7 on my domain. I wanted to add it my webpage into Google® Webmaster Tools (https://www.google.com/webmasters/tools). I verified ownership (of domain) and I tried to download my page as GoogleBot®, but I received this information : Unreachable page and information: 503 Service Unavaliable. The same happened when I registered on Bing®.

I don't know where is error. I can normally open my page in web browswer without error. Recently I changed server of my page, I would like to robots index my page.

I give you code of :

  • php.ini (I never edited it) :

It's very long, so I added in on github.com.

  • .htaccess

It's very long, so I added in on on github.com too.

If you need more files, I will willingly help.

Thanks a lot of any help,

You can see clearly that Drupal generated the 503 Service Unavailable error. When you put Drupal in maintenance mode, it serves this error to anyone who is not already logged in with sufficient rights. That includes Googlebot.

To resolve the issue, take Drupal out of maintenance mode.
