White Screen after User Wizard

[citapinc]

SugarCRM CE 6.2.3
PHP v5.2.9
MySQL 4.1.22
Linux Server

I've searched the forum for "White Screen of Death" but haven't turned up anything that can help me.

I just did a new installation of SugarCRM 6.2.3 on a subdomain and the installation went just fine. When you log in as Admin I get the new user wizard. At the end of the wizard all I get is a blank white screen. Pressing F5 does nothing. I close out of Chrome (IE8 does the same thing), enter in the URL for the SugarCRM CE site and I am into SugarCRM. However the next day when I log in I have the wizard again and back to square one.

I've checked PHP.INI and the settings are larger than required. For example, memory_limit is set to 128M and session.save_path is set to /tmp (which does exist).

Unfortunately, I don't have direct access to php.ini so I can't turn debug on, so what else can I check to fix this "white screen of death" issue?

I don't know if this is related, but MySQL 4.x is not supported. You need to be using either 5.0 or 5.1

Funny you mentioned that. Right after I posted the message it hit me that the MySQL Version wasn't 5 but 4. So this morning I had my hosting company setup a whole new server and made sure it was using MySQL 5. So now the server is running PHP 5.2.9 and MySQL 5.0.92.

I did a complete reinstallation of SugarCRM on this new server and I'm still getting the White Screen after the User Wizard.

AARRGGG!!!!

Here's an update:

1. I changed all folders and directories to permission 775 and still getting white screen.

2. Had web hosting company create a php.ini file in the CRM folder so I can put my own settings in place. I now have the following settings in the php.ini file:
date.timezone = "America/Los_Angeles"
max_execution_time=6000
upload_max_filesize=60M
memory_limit=256M
post_max_size=60M
I created a phptest.php file that runs phpinfo() and I confirmed that these settings in the php.ini file are in use.

Even after making these changes, I'm still getting a white screen after the wizard. I checked the server's error log and it shows no errors. I put SugarCRM in Debug mode and from what I can see it all looks good to me.

What else can I check to make this darn program work??????

I got so fustrated with SugarCRM tonight that I completely uninstalled the software off our server, deleted the MySQL database and I'm starting all over again. This time instead of using the installation script that is part of our web hosting package, I'm doing the installation manually myself.

I'll keep you posted.

UPDATE:

We got it figured out.

The issue was that SugarCRM was getting installed by a script on the hosting company's control panel. So I used the control panel to uninstall SugarCRM, uploaded the files manually and ran the install.php file myself.

Sure enough, the installation routine caught that PHP didn't have the MB String extension installed!!!

Once the hosting company recompiled PHP with the extension, everything came up and worked just fine.

So just because your hosting company has an automatic script that installs SugarCRM, it's still best to do the installation yourself just to make sure everything is setup properly.
