I'm having the following issue. My developers have made an update to a component we run on our SharePoint farm. For some unclear reason, they changed the public token of the assemblies in the wsp solution.
After clearing up all the issue I'm left with one problem:
When I want to look at a site in a web application with the wsp installed i have to following issues
On the server accessing the site using http://MyServer/sites/Site1
all web parts, including all of the OOB webparts, generate the following error: "Web Page Error: This page has encountered a critical error. Contact your system administrator if this problem persists." If I retract the solution from this web app, everything returns to normal.
While this happens no messages appear in the ULS although running on verbose
However when viewing the site on a client pc, the webparts run fine...
when using http://localhost/sites/Site1
on the server... the webparts also render correctly
Any ideas? Sites are always viewed in the same 'internet zone'
