After the update from 2.0.22c to 2.0.24c I get a blank screen when I try to create an invoice or delivery note on new orders.
This is usually the RAM, please try this version http://dev.virtuemart.net/attachments/download/660/com_virtuemart.2.0.25_extract_first.zip . If enabled on your server, it tries to allocate over 90 mb for pdf and sending the email.
No it did not work.
Which php setting should I look at?
The server is ISP so I don't know if I can change php settings.
On the server php memory_limit = 96M
Why is it ok for ver 2.0.22c?
In the Configuration page I had "Enable Joomla Plugin" ON
I disabled this and that fixed the pdf generation problem.
