Migrating from Joomla 1.5 to Joomla 3.0

I'm migrating my sites from Joomla 1.5 to Joomla 3.0. Part of this process has been using the back up and restore features to save my forms and then load them on my new sites. It seems to work fine for smaller forms, but when I try to restore larger forms and then go to edit them in Joomla 3.0, it just goes to a blank screen. The Joomla part of the page doesn't even load.

It's odd because the only difference seems to be the size of the forms. The larger forms also includes upload fields, if that makes a difference. Is this a known error? How can I get around it?

Thanks,
Zach

Update: This error also occurs when I try to change the editing wizard from Advanced (which is default for 3.0) to Easy (which is what I'd originally built the forms in.

Hi Zach,

Not something I've seen reported before. Please set your site Error Reporting to Maximum temporarily and see if you get a more helpful error message.

Error messages:

When importing, the table connected and admin panel columns read:
Warning: array_key_exists() expects parameter 2 to be array, null given in /var/wwwjoomla/structuralpackagingsummit.com/administrator/components/com_chronoforms/chronoforms.php on line 25 (This may or may not be part of the issue).

When opening form editor:
Fatal error: Allowed memory size of 26214400 bytes exhausted (tried to allocate 5415147 bytes) in /var/wwwjoomla/structuralpackagingsummit.com/plugins/system/advancedmodules/advancedmodules.php on line 97

Upon further investigation, this appears to be a conflict between Chronoforms and the Advanced Module Manager Plugin from NoNumber. It's still a bit odd because this conflict doesn't appear to be present on earlier versions of Joomla, but at least I know I can get rid of the advanced module manager to make it work.

Hi Zach,

I'm not convinced that there is any connection. The PHP warning is just a warning (annoying but not fatal). The timeout is presumably an un-checked loop the Advanced Modules code. I downloaded a copy and line 97 appears innocent - but it may just be the point where PHP timed out.

	/*
	 * Replace links to com_modules with com_advancedmodules
	 */
	function onAfterRender()
	{
		if ($this->_pass) {
			if (JFactory::getApplication()->input->get('option') == 'com_modules') {
				$config = plgSystemAdvancedModulesConfig();
				if(!$config->show_switch) {
					return;
				} // this is line 97
				$body = JResponse::getBody();
