Hi,

Just recently upgraded a magento installation, but im seeing the following error:
We are running 1.4.1.1

Anyone got any ideas as to what could be causing this issue?

anyone got a suggestion?

 

On times during upgrade some files are not modified due to permission issues.

So you need to check the diff files manually to make sure upgrade was successful.

Also U might have to make sure all sql update queries were fired.

Apart from these two things if anything was modified in the core files then too as the code has been overwritten error might be there.

So cross check upgrade using diff files.
