Can you delete the files under the "templates_c" directory and then view one of your individual archives pages and see if it still gives you that error? Either do that or edit your individual archive template which should invoke a rebuild of that template.
I did both and still got the same error. Those files appear after the first hit to a individual archive page. I cracked one open and there doesn't appear to be any errors inside, just php code. Line 194:
CODE
$email = "{{MTCommentEmail|sanitize:"1"}}";
More details on my .htaccess. It has rewrites and redirects in it. The redirects and the rewrites are to facilitate using FeedBurner to do it's thing to my feed and to make sure that dynamic publishing worked in the first place. I knew it was gone when I got an error message in my email saying that individual archive links didn't work and I had not remembered deleting it (since I had no reason to), so I assumed that MT may have had something to do with it.
Details of my host's config:
* PHP version 4.3.9
* Apache 1.3.31 (Unix)
As far as the upgrade itself went, I simply uploaded the upgrade files and did a rebuild as a check. If there was anything else I needed to do, I was not aware.
