CiviCRM Community Forums (archive)

Whatever I do, I can't get around the white screen.

Civicrm and drupal runs perfect on my local installation. Four days ago I tried to upload everything to a shared web-hosting.
Drupal runs fine but as soon I enable civicrm everything turn out to be a white screen. I went into the system table to disable civicrm.

Maybe important to mention is:

• I don't have access to the apache log files
• I increased the PHP memory (128M)
• I also added php_value error_reporting E_ALL into the (dot)htaccess file

If it's not a memory problem then it must be a configuration error, but I don't see any error or warning messages on my screen.

this are the settings in civicrm.settings.php

}

// force PHP to auto-detect Mac line endings
ini_set('auto_detect_line_endings', '1');

// make sure the memory_limit is at least 32 MiB
$memLimitString = trim(ini_get('memory_limit'));
$memLimitUnit   = strtolower(substr($memLimitString, -1));
$memLimit       = (int) $memLimitString;
switch ($memLimitUnit) {
    case 'g': $memLimit *= 1024;
    case 'm': $memLimit *= 1024;
    case 'k': $memLimit *= 1024;
}
if ($memLimit >= 0 and $memLimit < 33554432) {
    ini_set('memory_limit', '128M');
}

Is there a way to troubleshoot a white screen (without log files). I tried everything mentioned in the previous posts.
Many Thanks,
Chris

I enabled display_errors. It showed a warning that wasn't related to civicrm. The warning was to set the php_value allow_call_time_pass_reference on True.

I added the value in (dot)htacess. The warning disappeared.

Hereafter I enabled civicrm again, but it was still a blank screen. 
The watchdog table didn't show me any related errors. Is it actually possible to run civicrm on a shared hosting?

thanks,
Chris

You might want to check: http://nz.php.net/manual/en/function.mkdir.php

and then put some debug statements in: CRM/Utils/File.php (function createDir, line 108) and try to figure out what needs to be changed to convince apache/php to create a directory that it can read/write

You might also want to check: http://nz.php.net/manual/en/function.umask.php

we dont test with safe_mode and/or open_basedir. So not sure if its a side effect of that. You might want to do some web searches about it, which might help

I had the same problem and finally tracked it down:

When I design the site locally, I'll untar the archives manually, then I'll upload the files and folders via FTP to the server. Usually this works fine, but with CiviCRM it looks like there's a problem doing this with files in the Smarty folder.

Check the Smarty messages to see if the file it's looking for is actually where it's supposed to be; when I looked, I saw the filenames had gotten corrupted in the transfer - instead of having names like core.assemble_plugin_filepath.php, the names had been copied as core.assemble_plugin#6BD9B7.php. I recopied the files and renamed them as I went; you could probably just rename the files on the server using your local installation as a guide.

Hours and hours tracking this down - hopefully this will save someone else some time, as those of you in the Drupal community have saved me. Now if only someone could tell me how to import and export CiviCRM databases using phpmyadmin, that would be great - Drupal works like a charm, CiviCRM not at all for me...

I was able to solve the problem - it had to do with two things: different versions of PhpMyAdmin on server and local (Drop Tables needs to be enabled), but the main problem was doing DB manipulation while I was still logged in. Once I logged out and logged back in, the "foreign key" errors went away.

Insofar as it's a new install, I wasn't concerned with the data - if I can ever get CiviCRM working (see below), the information will come in handy when I need to migrate in the future.

I have another, more serious problem that I've posted here: http://forum.civicrm.org/index.php/topic,2908.0.html - DB errors when trying to add Event Types and/or Activity Types.
