Tonight I upgraded my DNN installation from 4.8 to 4.9.  I backed up my web.config, uploaded the upgrade files, then applied the normal web.config changes to release.config (machine keys, db qualifier, dbo, etc.).

I forgot to set AutoUpgrade to false and I believe that someone hit the page before the upgrade files were all in place, because now when I attempt to run:

http://mydomain.com/install/install.aspx?mode=upgrade

I get only a blank page.  The upgrade does not appear to run.  I have copied the file again and tried to run the upgrade again, but still I get only a blank page when I run the upgrade

So now I'm experiencing some bizarre website behaviours:

• I can see my home page, but when I click on Login or Register, it just refreshes the page ( I don't even get presented with a login or registration page)
• When I type in www.mydomain.com, the browser shows the site IP address, which happens to be the first portal alias
• All this same behaviour happens on all the portals

Is there something else I should be checking/running/looking at to force the upgrade to run again?

What does this odd behaviour indicate is wrong with my upgrade?

Thanks for you response.

First, I'm not following you about adopting the web.config manually since 4.6.2.  Can you clarify that?  Do you mean that something in the upgrade process will move all my settings over?  How does that work?

I did a couple refreshes of both the full upgrade set of files, plus the web.config and never got the website to respond correctly, so I restored from backup to my pre-4.9 state.   My site is working again, but chewing up massive amounts of memory and CPU, so my hosting provider is screaming to get this fixed (rightly so).

I am experiencing the App Pool reset issue in my logs - about every minute, which is probably due to the App Pool recycling.  This was happening before the 4.9 upgrade attempt -- that's why I was hoping the upgrade would work.

I'm also seeing something odd just before the app pool recycle:

So about every minute or so, something is hitting my site looking for this URL.  This is partially and old URL from our previous site (notice the ending in .htm), mixed with the default.aspx page.  I've checked our SiteUrls and we don't have any special entries for this.

I don't know if this is related, but I thought I'd post it as well.
