CodeIgniter vs Godaddy Problems

Hello every one. I’ve been planning for this post long. But couldn’t manage time. This is about a problem i have faced during my freelance work on mid August for a client in Bosnia. My web application was built with CI and was working fine in local as well as remote server. But was causing problem on clients Godaddy server.
Problems were:

1. It was giving problem ‘404 Page Not Found’ when requesting default route.
2. Request with full url with controller was giving ‘No input file specified’. Which was solved by putting ‘index.php?’ in the config file. But i want to remove the index.php from the url. Have tried all the .htaccess settings suggested in the forum.
3. All the database transaction gives a error like below:

A PHP Error was encountered

Severity: Warning

Message: mysql_real_escape_string() expects parameter 2 to be resource, boolean given

Filename: mysql/mysql_driver.php

Line Number: 227

After that i tried some suggestions from this user guide page. Which actually solved my problem No. 1 with changes in config.php like below:

$config['uri_protocol'] = "QUERY_STRING";
and
$config['uri_protocol'] = "ORIG_PATH_INFO";

Other settings were either failing or was giving me the default controller for all the url i request for. But my problem No 2 and 3 was still on loose.
Then again i’ve started to investigate and found a problem of database connection. Actually i was so sure that DB connection settings problem will show me an error on initial stage that i’ve never double checked the DB settings. But for some weired reason, CI doesn’t show any error on DB connection problem over Godaddy. So beware of it.

So after rechecking the DB settings my problem No 3 was gone. Now lets see the .htaccess settings for problem No 3 which works under Godaddy server:

Options +FollowSymLinks
Options -Indexes
DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|img|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]

Additional to the solutions above, also try to re ftping your scripts. Just in case. Also some others suggested me to avoid this host to save time :-).
Whole thing was done with suggestions and help of great CodeIgniter forum. You can get further help and old discussions over there.
You can also visit my clients site here. Which (thanks God) is running smoothly ever since.
Thank you all.
