Browse media library not opening

1.3k views Asked by At

We are using Sitecore 6.5 and the Browse link on images within the CMS backend is not opening up the window to select an image. A blank window just appears.

There is nothing in the Sitecore logs or window event logs. This used to work - when I compare the bin folders with the previous version, I only see a difference in the version of mscorlib.dll

I don't know if this is related, but when uploading a package we get the error

[ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.]
   System.Reflection.RuntimeModule.GetTypes(RuntimeModule module) +0
   System.Reflection.RuntimeModule.GetTypes() +9
   System.Reflection.Assembly.GetTypes() +143

The problem was the \sitecore\shell\applications\Media\MediaBrowser\MediaBrowser.xml file was complete empty.

We have no idea how this happened. Restoring the xml fixed this issue.

I've seen something similar to this when the source path specified on the field was set to an invalid folder. If you take a look at the field definitions on the template, do they have a folder specified for the image location? Is that folder still valid?
