Please bear with me, we have an special case / problem that we have inherited through a new client.
Our client has a website that was built upon Umbraco; an apparently modified version that the origianl developer refuses to provide because it is 'their' code. So, we have an issue where the client is stuck trying to find another developer (us) to help make edits and bare-minimum changes until a new, fresh site can be built.
With that in mind, we have taken a copy of their current Umbraco 4.6.2 installation from their live site, along with a Database backup, and installed them locally on our dev server. This is obviously not an ideal situation, and errors are not a surprise, however i am unable to figure out what this error is telling me: (Any insight would be much apprciated)

Can you get in to the back end of Umbraco? Is it using XSLT or MVC?
If you can in to the backend umbraco it maybe worth just creating a node and trying to preview that to assert its a problem with XSLT or something else first :). Charlie.
yes I can 'get into' the back end, meaning it runs, although it too shows similar error messages at times. I clear my chache/cookies frequently, I don't believe it is related to cookies or sessions.
I am unsure if web.config is 'correct' per se, in that it is correct for the Production site. This is a live running 4.6.2 site without source code that we are adopting.
i should also be clear, we are new to Umbraco. I have successfully installed a fresh, current version on my local workstation, but that was through Web Platform Installer, which was about as easy as you can get. it didnt give me any insight on installing a compiled version :/
Imagine, if you will, downloading the site files through FTP, and setting up a copy of the DB on another SQL server (internal network).
Can you tell me if you are using XSLT and what does the content tree look like? Have you published all the node in the tree? (Right click on content then select publish)
Have you tried to preivew any nodes in the content section? Does this work?
I am guessing that the content is not published so the xslt script you are running cannot find any XML. :)
It turns out one for sure problem was the umbracoLogs table was MASSIVE and causing timeout errors in the CMS
these are no longer happening since truncating the table.
However, I am still having issues on the front end that seem to be pointing to... Courier?
I don't know if even the client knows if they have Courier installed. it could be that we are using our own sub-domain for testing and it is not a 'registered' domain in Couriers licensing?
i don't know, still trying to understand all this.
