Cannot Upgrade AIO from 2.0.0 to 2.0.18a

[BD3]

I upgraded VirtueMart to 2.0.18a from 2.0.0 and then tried to upgrade AIO both with the UI and manually. I then receive the following error:

Code Select Expand

Checking VirtueMart2 modules...
Fatal error: Call to a member function getDBO() on a non-object in /home/content/html/administrator/components/com_virtuemart_allinone/script.vmallinone.php on line 530

Going to any product or catalog page throws this error:

Code Select Expand

Fatal error: Call to undefined method VirtueMartModelCategory::addImages() in /home/content/html/components/com_virtuemart/views/category/view.html.php on line 64

I am running Joomla 1.5.21. Any thoughts?

Also jumping directly from version 2.0 to 2.0.18a might be a little bit too high and probably causes a few hickups.

Hey, thanks for the post. I really appreciate it! Have been scratching my head for a few hours, but that makes sense (2.0.12+ no longer supported with Joomla 1.5x)

Something else just came into my mind and you should try this. The 2.0.18 AIO zip file is slightly larger than 2mb. Please read this:
