trying to upgrade 1.7.1 to 1.9.2

[fatih]

Hello I am trying to upgrade 1.7.1 to 1.9.2. I uploaded all files to ftp but I have mistake when I import xml.

Callback NFLJ_Showcase_Listener_Proxy::extendPostController is invalid (Invalid Method).

How can I solve this errror?

Try uploading the files again, make sure that if you have ANY kind of server file caching, that the cache is flushed. Then try and run the XML again.

Thanks Bob. You are right. I flushed cache. now it is OK.
