TYPO3 Core

Hello,

We did some changes on our server We enabled mod_deflate to enable gzip-ing webpages. Before this was done, site made with typo3 worked fine.

Now, after changes made on the server, when we try to access our "typo3 site", it doesn't show up. White page accurs.

We followed instructions on page http://dmitry-dulepov.com/article/blank-empty-page-in-typo3.html#ixzz1AF5k98jI to see errors. We can not see them.

Instructions were:

1. Go to the Install tool
2. Select "All configuration"
3. Set displayErrors to 2
4. Add your IP address to devIPmask

Our install tool (www.this-is-only-example.com//typo3/install/index.php) is not available. Therefore we made changes directly in file - t3lib/config_default.php

Settings:

1. 'displayErrors' => 2
2. 'devIPmask' => '127.0.0.1,::1',

IP 127.0.0.1 was changed to our IP

After this was done, we still get only white pages. No errors are shown. We still can not access install tool. All we get are white pages everywhere:
www.this-is-only-example.com/
www.this-is-only-example.com/typo3/admin
www.this-is-only-example.com//typo3/install/index.php

But!
There are some pages that shows up in fileadmin directory. Eg.
www.this-is-only-example//fileadmin/template/subpage.html

How can we see what is going wrong?

Please help and thank's for the answers.

If we try to see the source of the page with Firebug in Firefox Browser, we get this:
