Could not load type 'EPiServer.Editor.Tools.ToolBase' from assembly 'EPiServer'
We solved the problem. It was an old third party dll in the bin folder that had a reference to EPiServer.Editor.Tools.ToolBase.

It wasn't ImageVault was it? I have the same Issue with a site using ImageVault 3 and the ImageVault.EPiServer6 Dll is likely what is causing it :)

This thread is locked and should be used for reference only. Please use the Episerver CMS 7 and earlier versions forum to open new discussions.
We are updating a site from CMS 6r2 to CMS 7 that previously also was updated from CMS 5.
The upgrade process went well, and all compilation errors and warnings are fixed.
When surfing to the website we get a yellow screen of death saying:
"Unable to load one or more of the requested types. The following information may be a subset of the Type/LoaderException information present - inspect with debugger for complete view.
Check assemblies [] and/or types []. Information from LoaderExceptions property [Could not load type 'EPiServer.Editor.Tools.ToolBase' from assembly 'EPiServer, Version=7.0.586.1, Culture=neutral, PublicKeyToken=8fe83dea738b45b7'.]."
We think that it has to do with the CMS5 editor that is no longer a part of CMS 7 and no longer supported.
Before upgrading we changed all propertyLongString to use PropertyLongStringControl instead of LegacyPropertyXhtmlStringControl in web.config. No pages are using the old editor anymore, and we are not refering to the old editor in code.
Our EPiServer log file says:
ERROR [1] EPiServer.Framework.Initialization.InitializationEngine.SetupAssemblyTypeScanner - Type lookup failed

Any ideas on how we can solve this problem?
