I had fallen a couple DNN YAF versions behind. A week ago I updated YAF to the latest available from CodePlex. I find that some of my users can't access the forum and that some thumbnail images are missing. For example, my personal avatar is missing. I get a broken image link.

I hope this will help to resolvethe issue.

I was going to try removing the DNN user importer and adding it back in case maybe something had changed with the script. When I clicked the buttom to 'Delete YAF User Import Schedule', I get the error: A critical error has occurred. Unable to cast object of type 'System.Web.UI.WebControls.LinkButton' to type'System.Web.UI.WebControls.Button'.

My event log is also explofing with the following message or similar:

I also see messages like this:

It might be worth noting that I use an object qualifier as defined in web.config.

Both issues will be fixed with the next version.

The DNN version is 07.02.02 (303) and yes, content localization is enabled.

It will take some time until the next version is out, but i can update the current build version with the fix as soon as possible.

P.S: to stop the error logging, you can disable the error application errors in the yaf host settings under logs.

I initialy got onto DNN because I knew that I needed to spend more time running my business and less time dealing with merging of various software and technology. It's guys like you that take the time to produce modules like this that make it possible for a small business like mine to compete with large businesses. THANKS!

When I right click the prioperties of my broken thumbnail image it shows as follows:

DNN provided web pages show my avatar correctly. Right clicking on it shows this far different hyperlink:

http://simxperience.com/profilepic.ashx?userId=1&h=32&w=32&cdv=635462034032080034 

Unfortunately the avatar's are still broken images.

I also tried clearing the DNN cache
