Hey,

When I look in my Event Viewer I see the following error on many of my pages from BOTs (All of which I can access without a problem). I am not sure why I am getting these errors. I upgraded a few months ago from DNN 4.3.7 to DNN 4.9.5.

I also get the following error frequently also... it appears it has something to do with the Links Module I believe as the RaqURL is /LinkClick.aspx

Any ideas on either of these?

Thanks for all of your help!!!

This is a known issue, the first one is due to the app_browsers data being out of date with DNN 4.9.x in relation to the bots, and version information is not updated. The second is just an invalid link. You can disregard the errors...

You can get the latest DNN browser definitions here: http://owenbrady.net/browsercaps/ If Voila is not in there, add it yourself or in my case, I asked Owen to add it for me and he graciously added it for me.
