Few days ago, early in the morning, connecting to my DotNetNuke site I found it completely crashed!
Apparently without a valid reason, given that I left it in good health the night before... everything was ok and I didn't make any config changes.
Giving a look at the log, the main exception (at which many other followed) seemed to be this:
"System.Web.HttpCompileException: \Portals\_default\Skins\Tranquility\Basic.ascx(32): error BC30560: 'admin_skins_solpartmenu_ascx' is ambiguous in the namespace 'ASP'."
After 5 minutes of panic, I started to look for a known solution on the internet and on dotnetnuke.com forums.
I didn't find many solutions... and the few ones I found didn't match my case.
For someone the exception arises due to the existence of an "admin" virtual path
Others state that is a naming conflict and a renaming is enough to fix the bug
In some other cases seems to be a lower-upper case problem
However, in all situations above everything started after a modify, an external input... thing not true in my case. My provider too assured me that no modifies or patching activities was done during that night.
At the end I solved this way:
- set to true the debug mode in web.config: <COMPILATION debug="true" strict="false">
- restart the application connecting to the home page
- re-set to false the debug mode in web.config: <COMPILATION debug="false" strict="false">
The mistery about the exception remains... if someone know a clear explanation, please, post it on the blog.. just to avoid the "An error occurred" panic! ;-)

Re: Error BC30560
Thanks for this solution. Actually I have suddenly found this error on 5 dnn sites and I too was looking at ISP updates. I was also looking for old dll namewspace conflicts but now . . .
Lets hope it sticks.
Thanks

Re: Error BC30560
After chasing this around for a while, I found that it was a duplicate .ascx file appended with _old having the same namespace. Once I deleted that it immediately worked without any further action.

Re: Error BC30560
Hi,
I have encoutered this problem today. This error appear suddenly without any changes to dnn or user controls!
My workaround was:
1) Stop Web service
2) Delete all folders and files from: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
3) Restart Web service
That's all!

Re: Error BC30560
Gilles Le Pigocher, Thank you so much!! We bought a 3rd party intranet suite built on ASP and they couldn't figure this out! You saved me a lot of typing and importing.

Re: Error BC30560
Thank you. This hit several of my production sites this morning and I was stumped. Sites are back up now. I love the fact that a post written in 2007 is still helping to fix sites in 2012!
