In MT RC3, there is some problem when I want to publish it or delete some entries.
Even I upgrade to MT 4 final. This problem still here.
It shows the error message like below:
Can’t call method “archive_label” on unblessed reference at lib/MT/App/CMS.pm line 14152.
I checked the Movable Type 4.0 Upgrade Guide.
And later I got the answer.
The guide said some Plugins Should Be Removed.
So, in the backend, system, plugins, I disabled two plugins.
# Date-based Category Archives (provided by MT4 betas)
# Author Archives (provided by MT4 betas)
And also I remove the file:
Then this error gone. I can publish as normal.
