Installing and upgrading help

I hit this problem the other day on my development server. I think they recently made the checks that the installer does stricter.

In the 

$CFG->dboptions = array(
// ...
);

bit if your config.php file, make sure you have set

    'dbcollation' => 'utf8_bin',

 as one of the options.

I am wondering if the only serious problem might be that you forgot to set "collation" to utf8_unicode_ci in your database.  I do this using phpMyAdmin in cPanel.  This should remove the "red" check.  The "yellow" warning might not bother the install.

In addition to and for your future reference, linux (thanks for including the server setup) doesn't use .dll extensions to php.  .dll's are Winders.  So when reading instructions, one has to sometimes translate platform information provided.  Just one more bit of info next time: hosting provider.  Who?  All are NOT equal. :|

Apparently, you are remotely hosted.  Some settings for PHP cannot be set via .htacess.  PHP_INI_PERDIR (per directory), PHP_INI_SYSTEM (the system php.ini not the customer php.ini), and PHP_INI_ALL (all).

Reference: http://php.net/manual/en/ini.list.php

If the php-intl extension does not show in a phpinfo out put, more than likely one cannot add an extension on shared hosting.  Check with hosting provider.
