Hi there, 

I'm installing uBlogsy onto my existing site. I use ublogsy on pretty much every site i build and it works great! This is a new error i've come across wondering if anyone else has had it or can give me a little point in the right direction. Here is what the error is from log file: 

2013-04-22 09:38:15,034 [27] ERROR Umbraco.Web.UmbracoApplication - [Thread 88] An unhandled exception occurred

It breaks the whole site and shows this error until i delete the ublogsy dll's and it works again so i can uninstall it. I've checked to see if i had any faulty DLL's but everything seems ok and the usual files in there as i only have two packages installed google maps and image gen and i've tried installing uBlogsy withouth those two on to see if they were causing the error and still the same. 

Umbraco Version : 4.11.6 (Assembly version: 1.0.4834.19775)

ASP.Net Version : 4.0.30319.17929

IIS: 7.5

I'm using the same umbraco version i do for all other sites and uBlogsy is fine. Any ideas? 

Thanks
