WSOD Question

I'm developing with CI 1.6.1 under windows/apache/mysql and have a noddy app reading & writing to mysql fine.

When I move the app across to a linux box (ubuntu6.06LTS) I get the WSOD, nothing is logged to the log files or anything; the application completely dies.

I initially thought it was a problem communicating with mysql so I wrote a simple php page to open a connection outside of the CI framework, and this works fine.

If I remove database connections from the CI application the it works again, so I suspect there's something within the CI project that is barfing giving me the WSOD.

Has anyone got any suggestions please?

Thanks a lot.

let's start by see what is into your config/databases.php file and remove your password indeed.

Thanks for your reply. Ok the CI stuff is below

config.php first - comments removed
$config['base_url']    = "";
$config['index_page'] = "index.php";
$config['uri_protocol']    = "AUTO";
$config['url_suffix'] = "";
$config['language']    = "english";
$config['charset'] = "UTF-8";
$config['enable_hooks'] = FALSE;
$config['subclass_prefix'] = 'MY_';
$config['permitted_uri_chars'] = 'a-z 0-9~%.:_-';
$config['enable_query_strings'] = FALSE;
$config['directory_trigger'] = 'd';
$config['controller_trigger'] = 'c';
$config['function_trigger'] = 'm';
$config['log_threshold'] = 4;
$config['log_path'] = '';
$config['log_date_format'] = 'Y-m-d H:i:s';
$config['cache_path'] = '';
$config['encryption_key'] = "";
$config['sess_cookie_name']        = 'ci_session';
$config['sess_expiration']        = 7200;
$config['sess_encrypt_cookie']    = FALSE;
$config['sess_use_database']    = TRUE;
$config['sess_table_name']        = 'ci_sessions';
$config['sess_match_ip']        = FALSE;
$config['sess_match_useragent']    = TRUE;
$config['sess_time_to_update']         = 300;
$config['cookie_prefix']    = "";
$config['cookie_domain']    = "";
$config['cookie_path']        = "/";
$config['global_xss_filtering'] = FALSE;
$config['compress_output'] = FALSE;
$config['time_reference'] = 'local';
$config['rewrite_short_tags'] = FALSE;

$active_group = 'default';
$active_record = TRUE;

$db['default']['hostname'] = "localhost";
$db['default']['username'] = "mgb";
$db['default']['password'] = "mgb";
$db['default']['database'] = "mine";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = FALSE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";

The following in a standalone page connects ok:

$link = mysql_connect("localhost","mgb","mgb");
if( !$link ) {
echo 'No';
echo 'Connected';

I do find it surprising that CI doesn't log anything at all....

Cheers for any suggestions / tips

Does the default CI install work? Can you see the welcome page just fine?

Yes, the default CI install works fine and my noddy application works as expected if I don't attempt to access a database.

It's when I try to reference a database that I get the WSOD, no html is rendered to the browser at all, and I don't get anything logged to log files either.

It's very weird. I get this problem on two different boxes running ubuntu6.06LTS - one's a vmware box and the other is a dedicated server.

I think I'm more 'concerned' that the CI framework doesn't write to the error logs as I'd expect...

I may try to reimage a server with a different distro and see what it's working hunky dory for me on my windows development platform.

My development server is an ubuntu fiesty vmware server also. The only time I got the WSOD on it was when the log directory wasn't writeable by apache. And it happened as soon as I turned logging on in the config. Check your logging and cache system folders and make sure they are writeable.

bcdennis you're a star - you solved the problem!

My /var/www directory was writeable by apache initially, but when I uploaded the application with changes to write to the database, WinSCP changed the permissions back to non-writeable for apache, and I hadn't noticed....doh!!

I'll slink-off and hide somewhere Sad

Thank you to everyone who helped.

Hey, no need to slink off anywhere! We want you here Wink

Funny, as we were developing for EE 2 last week, there was one point (I was pretty sleep deprived in my defense) where I lost probably 3 hours over typos, and glaring omissions. Derek Jones (the other Tech Architect at EllisLab) and I would frequently have late night conversations that followed this pattern.

"Blarg, why isn't $this_thing working?"
"paste your code"
"sure, here it is, but you won't find it, I've been...."
"typo line 58"
"but I... ugh..."

I don't care if you've got 1 month or 1 decade under your belt, those types of things just happen sometimes Wink

Ha thanks Derek - I'll be hanging around as I love using CI and I'm really impressed by the helpful community too.

Like you say, somtimes it's the little things that are so easily missed which a fresh pair of eyes can pick-up immediately Smile

Again thanks for everyone's help
