We upgraded from 7.0.103 to 8.0.21 last week and since this moment, none of the WebPArts I created are working (error loading the WebPart ... of type ...).
I also get an error message in the shopping cart (function GetImageDocument not defined !).
What can I do to solve these problems ?
All the best,
Did you run the code upgrade tool against your code? Did you upgrade your custom webpart code? What errors are you finding in your event log?
Thanks for your help. I changed a few words in the code and the result is really better.
