"Undefined Offset: 0"

After searching this forums I added '3' to version table and I got:

"PDO: Table 'my_controlli.tags' doesn't exist2

I searched the forum again ad created the table as defined in base.php file only to get the same timezone error again.

My installation went like this:

• changed permissions (a+rwX) and copied files
  
• created config.ini with proper mysql data
  
• modified RewriteBase in .htaccess
  
• manually created the "tags" table (it wasn't there)
  
• manually added '3' to "version" table (it was empty)

All I get is 500 Internal Server Error:

date() [<a href='function.date'>function.date</a>]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Berlin' for 'CEST/2.0/DST' instead

Shared hosting is running PHP 5.3.10 with "internal" timezone database and "Europe/Berlin" as default timezone. Mysql is version 5.1.49.

Based on forum issues I also tried:

• adding a php.ini file with one line (date.timezone = "Europe/Berlin";)
  
• modifying selfoss/libs/f3/base.php trying to set the same timezone

and reverted to original.

Any help?
