Upgrade from 1.1.9 to 2.0.22b results in HTTP 500 error

[Nemonic]

Before I start, I am a complete noob to Joomla/Virtuemart but have enough experience with PHP/MySQL to muddle my way though most tasks. I've moved the site to a test domain and updated virtuemart.cfg.php to reflect the different domain.

Current versions:
Joomla 1.5.26
Virtuemart 1.1.9

Following the steps from this tutorial, Virtuemart 2.0.22b installs without errors however the shop is not accessible after the install. All I get is a HTTP 500 error. Any ideas?

Here's the results from the install:

Code Select Expand

alterTable ADD jos_virtuemart_order_items.product_discountedPriceWithoutTax : ALTER TABLE `jos_virtuemart_order_items` ADD product_discountedPriceWithoutTax decimal(15,5) FIRST

alterTable CHANGE jos_virtuemart_waitingusers.notify_date : ALTER TABLE `jos_virtuemart_waitingusers` CHANGE COLUMN `notify_date` `notify_date` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP


Table updated: Tablename jos_virtuemart_order_items dropped: 0 altered: 0 added: 1
Table updated: Tablename jos_virtuemart_waitingusers dropped: 0 altered: 1 added: 0

Install Component Success

Our suggested path is for your system /home4/marishaw/public_html/vmfiles, use this link to the config

Here's the error I get when I click "go to shop" immediately after the install:

Code Select Expand

The website encountered an error while retrieving
http://www.marishawaii.com/mera/administrator/index.php?option=com_virtuemart&task=disableDangerousTools&token=992b9a76e12b7565c64bad65437e5d8d.
It may be down for maintenance or configured incorrectly.

And if I go to the store directly:

Code Select Expand

The website encountered an error while retrieving
http://marishawaii.com/mera/merastoredirect.html.
It may be down for maintenance or configured incorrectly.

Which to my eyes make sense because there is no merastoredirect.html, except there never was a merastoredirect.html and it worked before.  I can only assume that's because it's a fly page and is generated by virtuemart but I have no idea where to even start to try to solve this. Any help offered will be greatly appreciated!

Did you do the migration with some form of SEF enabled? Obviously the error is something related only to your site.

The preferred migration scheme is http://docs.virtuemart.net/tutorials/30-installation-migration-upgrade-vm-2/77-upgrading-vm1-to-vm2.html

Well... that was interesting. I disabled SEF urls, cleared my cache and verified that it worked before trying the upgrade again. This this time without renaming the com_virtuemart folder (that's the only real difference between your preferred method and the link I posted). I'm not getting an error anymore. I'm not getting anything else either, a complete blank page on both the shop and the back end.

Edit: I take that back, I am getting the HTTP 500 error for both the store and the back end. Had to clear my cache again before I saw it though.

There is a sticked thread in this forum section. Non official manual for migration.

Thanks but I've been through the stickies and searched this forum extensively. None of the guides posted have mentioned this particular issue. I guess I should have mentioned this in the first post but I wouldn't be asking for help if I hadn't already scoured the interwebs. I'm still searching though and if I find a fix I'll be sure to post it here but any insights or suggestions you are always appreciated.

Some other fixes I've already tried:

You could pm me access and we will try to migrate successfully.

Wow! That would be amazing. I've gone through and disabled/uninstalled most of the components, just in case any of them are the problem but still no luck. I'll restore the working 1.1.9 backup with all the components still enabled and setup a FTP/cPanel account for you, then PM you the details. Thanks so much!

Next time I'll check what error did you have. Probably you made installation/migration of VM2.0.22b onto Joomla1.5.




VM2.0.22b can't launch on Joomla1.5. That's why you have this error. You need to migrate then to Joomla2.5 and repeat migration process then.
