[SOLVED] CB and CBSubs blank pages after PHP upgrade

Hi,
I've got a rather urgent issue with CB and CBSubs.
J 2.5.11
CB 1.9
CBSubs 3 (most recent version)

After upgrading my server to PHP5.3.23, registration form, all cb member listings, login module return blank pages. Forum discussions on this don't appear to be my problem.

Debug and max error reporting return NO error messages.

In administrator, I get blank pages on CB User Management, main Paid Subscriptions page, Settings, and several other submenu items. I can see the other CB tabs (except User Management) and other Paid Subscription submenu items. When I try to close the sub menu items, I get a blank page.

The most interesting part of my issue is this. I have a subdomain where I installed CB only (no CBSubs) in late March. That site has none of the issues I'm seeing with the main domain.

epicorg.com is the main domain. newvoicesyoungwriters.com is the subdomain.

I've used my golden ticket on this, but figured it was good to get this into the forum so others might be helped.

SU info is in the ticket.

Any ideas what's going on?

Is this something that others have seen.

Enable debug mode and maximum error reporting in Joomla global configuration then duplicate your issue and see if the error exposes further. Most likely when you upgraded PHP versions you lost PHP.ini settings or are using a new PHP.ini file that has configuration issues. Please also see our FAQ below regarding blank pages.

thanks for the response, Kyle.

I found the blank page faq last night, but really didn't understand what I needed to do. This was particularly confusing to me:
if it the blank page is outside CB (no "option=com_comprofiler" in URL), e.g. in joomla during installation, add following to the index.php (or index2.php, whichever is in the URL) in frontend or backend where it gives you a blank page, just after the first " ini_set( 'display_errors', true ); error_reporting( E_ALL );

Since this problem only affects CB and CBSubs I'm assuming this is NOT outside CB, so I'm assuming this doesn't apply to my issue.

I have url rewriting turned on. Here's the registration page:
epicorg.com/component/comprofiler/registers.html

I also tried the debug and error reporting and as I mentioned in my initial post, there were NO errors displayed. My server error log is also blank.

There's also the issue that the new CB installation on my subdomain isn't affected (apparently).

Your registration page is throwing a 500 error. That's a server error. You need to contact your host and also check server error log and see what's happening. Seams your PHP upgrade wasn't done right or PHP isn't configured right.

Now I'm REALLY confused. Why am I not seeing any errors messages at all? How did you get it to display? Where did you see it?

And I'm still not clear why the PHP upgrade would hose ONLY CB related items?

Will check with the host asap, but would appreciate you guys taking a closer look. I've given you the keys to the kingdom.

When navigating to the registration URL provided in your previous reply the below is thrown.

This is a server error. You'll need to check server error logs for details.

And I'm still not clear why the PHP upgrade would hose ONLY CB related items?

Not all usages are alike. CB could be using a PHP function your host has disabled. It could be any number of things. You'll need to check your server error log for details as to what's erroring. If nothing is showing then please contact your host and see if they can review their logs and see if anything is showing.
