Showing only blank page without errors

[eluser]drale2k[/eluser]
Hi, my CI setup is running at localhost without problems.

I use Windows with XAMPP local. I have uploaded everything to my root and edited all config files. I have no whitespace or something at the end of files and caching and logs are turned off.

I dont get it, it only shows a blank page without any source-code.

domain: www.md5hood.com/

Funny is if i call domain.com/cracker/index it shows blank page ( index exists )

When i call domain.com/cracker/index1234 a blank one comes too (index1234 does not exist)

Its confusing, someone knows what the problem could be?

I am using PHP5 and as said, local no problems.

logs are turned off

Turn it on and see if you get any errors logged.

In general:
Make sure file permissions are set correctly.
Enable error_reporting in index.php. If that doesn't work change your php.ini.

Code:

error_reporting(E_ALL);

Enable db_debug:

Code:

$db['default']['db_debug'] = FALSE;

Do you use a .htaccess file?

Ok this is the output of the log file. Looks like CI is in an endless loop? I cant see any loop in my code.

this can happen if you make a function with the same name as some new PHP native function.

also, triple check your whitespace.

[eluser]drale2k[/eluser]
This is my only controller, i dont see anything may looping. I checked for whitespace too, can there be any Win/Linux incompatibilities ?

Code:

<?php

/*
* @var string $result contains the result as output
* @var string $result_class contains the html <div> result class for the view file
* @var bool $found is TRUE if the hash was found, false by default
* @var bool $found_local is true if the hash was found in our local database, false by default
* @var string $hash contains the hash we are looking for
* @var string $source contains the source where the hash was found (local or remote providers name)
* @var string $table contains the MySQL table we will use

This is the Erroor log from CI http://nopaste.com/p/a9GFrPTkN

Please i need help, cant get my site working ;/

[eluser]helmutbjorg[/eluser]
My problem (which looks similar to yours) turned out to be with the .htaccess file.

This is what my htacess file looks like on my localhost which works fine

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php|cache|css|icons|javascript|themes|upload|user_guide|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]

But the solution to get it working on the live server (which took ages to figure out!!!)

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php|cache|css|icons|javascript|themes|upload|user_guide|robots\.txt)
RewriteRule ^(.*)$ index.php?/$1 [L]

Note the single question mark added at after index.php in the rewrite rule.

Hope that helps!!
