Safe Mode Hack again

[qrczak]

In http://dev.typolight.org/issues/1618 Leo say:
If you need the Safe Mode Hack, the install tool will ask you to enter the FTP details.

Now I want work on my client server, during installation TL didn't ask me about FTP details but System Check Tool say:

Create directory	•	Error	Error creating directory "typolight-check"
Create file	•	Error	Error creating file "typolight-check.txt"
You will most likely not be able to run TYPOlight without Safe Mode Hack.

so I assume that I need to use Safe Mode Hack becouse e.g. I can not set any settings becouse I'm not to able to write to localconfig.php file.
In this case I add manually to localconfig.php this:

$GLOBALS['TL_CONFIG']['useFTP'] = true;
$GLOBALS['TL_CONFIG']['ftpHost'] = 'ftp.server.com';
$GLOBALS['TL_CONFIG']['ftpPath'] = '';
$GLOBALS['TL_CONFIG']['ftpUser'] = 'user';
$GLOBALS['TL_CONFIG']['ftpPass'] = 'password';

But it's still doesn't work. How to add manually Safe Mode Hack in 2.8.1? Or I done right but someting is wrong with server?

When I try to install any extension via Extension manager I received:

Cannot create file "system/modules/catalog_ext/CHANGELOG.txt"
/www/mysite/system/libraries/File.php[107]

Maybe you need to add something like 'www/mysite/' or 'mysite/' as ftp path. (It should be the relative TL_ROOT path seen when you open a ftp connection.)

The smhcheck utility from the repository may also help you track down the issue.
