[Solved] Upgrade after server migration : blank page

[joebordes]

It is these two:
- AutoNumberPrefix
- PDFMaker

Just copy the AutoNumberPrefix directory to the new install. For PDFMaker you have access to the latest release, use that one.

AutoNumberPrefix should be updated as I haven't seen that one used anywhere lately, but, for the moment, try just copying it

Let me know how it goes
