All,

I upgraded to 0.8.0 and now I get an error when I try to run anything.  
See the examples below:

* * *

rake production radiant:extensions:gallery:migrate  
(in /home)  
Could not load extension from file: gallery\_extension.  
#\<MissingSourceFile: no such file to load – application\>  
Could not load extension from file: page\_attachments\_extension.  
#\<MissingSourceFile: no such file to load – application\>  
rake aborted!  
no such file to load – application

* * *

rake production ray:extension:update name=all  
(in /home)  
Could not load extension from file: gallery\_extension.  
#\<MissingSourceFile: no such file to load – application\>  
Could not load extension from file: page\_attachments\_extension.  
#\<MissingSourceFile: no such file to load – application\>

* * *

Do you know how I can solve this? I think it has something to do with  
the new Rails convention of appending “\_controller” to the application  
controller, but I am not sure why I see the error and apparently others  
don’t.

I’m having the exact same issue. Let me know if you solve it.

Hey Ben,

for me, setting config.cache\_classes to false (config.cache\_classes =  
false) fixed the error.

I haven’t yet exactly figured out why caching the classes breaks stuff.

Hope this helps,
