Contribution forms blank after 4.3.3 -> 4.4.6 upgrade

[iandees]

After upgrading from CiviCRM 4.3.3 to 4.4.6 my contribution form is blank. Other than this, the upgrade process appears to have worked without a hitch. When I turn exceptions on I don't see any exceptions displayed.

Any ideas for where to look to debug this further?

Typically, if a blank page appears, an error has occured, and should  be displayed or logged somewhere.  Have you checked all the logging / show errors settings in PHP and Apache, etc.? A bit of googling should help you find out where these are (hard for me to point you in the right direction since it depends on your server set up).

I can't seem to find any CiviCRM logs. The wiki doesn't seem to know where the log would be for the WordPress plugin:

http://wiki.civicrm.org/confluence/display/CRMDOC/Debugging+for+developers#Debuggingfordevelopers-Logfiles

My nginx error logs are empty.

Did you try looking in the PHP logs?

Are you able to get any errors displayed on the screen? Might be worth intentionally creating an error and ensuring that you can see that displayed on the screen.

If not, have a look at PHP error logging and ensure it has sensible defaults (display_errors, etc.)

On a slightly different tack, I'd review your contribution form settings, the amount sections especially. I had a similar experience and it turned out to be some combination of settings that didn't upgrade to a valid set of options (basically, the amount was missing).

I was able to create a PHP error from within the civicrm.php Wordpress plugin page by executing a function that didn't exist. I saw that get logged to my ngnix log.

I narrowed the problem down to this bit of code:

Code: [Select]

   
if ( $this->isPageRequest() && !in_the_loop() && !is_admin() ) {
      return;
}

I put a print in there above the return statement like so:

Code: [Select]

if ( $this->isPageRequest() && !in_the_loop() && !is_admin() ) {
      print "isPageRequest=".$this->isPageRequest().", in_the_loop=".in_the_loop().", is_admin=".is_admin();
      return;
}

and on pages that are blank I get the following:
"isPageRequest=1, in_the_loop=, is_admin="

Looks like Wordpress is broken maybe?

Getting there

I'm not a wordpress person so not really able to help here - sorry. Hopefully someone else will be able to...
