Server Error after installation: Cannot find/load Telerik.Sitefinity, Version=5.2.3700.0
I used the newest version of the sitefinity project manager to upgrade a site of mine and now the site only returns a server error when attempting to browse to it. The site compiles in visual studio with no problem.

The newest version is 5.4.
So if you upgraded from 5.2.
Try doing a full text search (ctrl+shift+f -> pick entire solution 5.2.3700.0) in Visual Studio for anywhere 5.2.3700.0 is used to reference a DLL. Then change that number to the 5.4 version number of the DLL and see what happens.
You need to make sure any references you had to 5.2 dlls are now to the correct 5.4 dlls.
Best regards,
Dave
You will also get this error if there's an assembly in your bin folder that was build against v5.2...do you have any marketplace controls or anything external to the webapp that would need rebuilding?
Thanks for the replys
@Dave I did an entire solution and project search for 5.2.3700 and nothing was found. Perhaps this means it's caused by what Steve said.
@Steve I'm not sure how to check if my assembly is built against the 5.2 sitefinity dll. How can I go about checking? (I'm only just learning to develop in C#) I don't have any marketplace controls nor do I have anything external I don't think. I do have a CRM SDK dll and an event registration dll that was created by some inhouse devs, but those dlls are apart of the project already and I would assume they would recompiled with the rest of the project. Regardless I'm pretty sure those dlls don't make reference to sitefinity's dll.
I reset my site and tried the upgrade process again but still no luck. I also tried to do a Rebuild and still the same error.
Any other ideas?
Hi Chris,
I can see that you are using the Sitefinity Sitemap Generator from Enterprisefinity. Probably this add-on is not built (yet) to the new version of Sitefinity, causing the error.
They seem to have updated their tool: http://enterprisefinity.com/products/sitemap-generator, but there are also some problems with it. I don't know if it is already built against the 5.4 hotfix that came out today?
Just check and make sure you're on the same version.
Kind regards,
Daniel
@Daniel Thank you, I think you are correct. I went and downloaded the 5.4 version of sitemap generator and replaced the DLL. This caused the error message to say I was now missing telerik.sitefinity version 5.4.4000 (since I am using the hotfix version 5.4.4010) It seems as of me writing this, entireprisefinity has not released a 5.4.4010 version of their DLL. I've emailed them requesting an update.
In the meantime, I've removed the sitemap generator dll and rebuilt my project. This allows the site to get to "The system is restarting..." screen but my page never ends up loading. I've tried restarting IIS and building again. Any ideas on why my site is not completing it's restart?
Wonder if it's related to it wanting to have the sitemap module there, like you'd need to edit the system.config and remove it
You could drop it back in and try assembly binding the Telerik.Sitefinity assembly
Thanks everyone, I'm up and running now.
It was stuck at "restarting..." because during my troubleshooting of the original problem, I attempted a rebuild (note to everyone, NEVER "Rebuild" a sitefinity project). Once I replaced all the dlls that rebuilding removed everything worked fine.
To be clear. My original issue was because an addon module dll was still referencing an old sitefinity dll version. Once I removed that addon's dll from the bin folder, everything worked fine. so Steve your original reply was spot on! The thing was that the module in question wasn't added to the project in visual studio, it was just a dll that I was instructed to drop into the bin folder.
