Hi, I'm having a similar issue I think, but my site is going down. I've done a restore with my host, and will upload the fix, I think the exception is the same:

Hi - I haven't looked at this issue for a while, or what preceisley what happens in DNN 5. If anyone has an updated .browser file, pls let me know.

My understanding was that this issue went away in DNN 5, so you didn't need a special .browser file.

Hi there!

I dhad the same issue and added Olivers "OtherSpiders.browser" File

This reduced the amount of errors in my eventlogs

But there are still other bots that cause this issue
One Of them is the "Yandex-Bot" as i mentioned ... this oneis also not included in the browser-caps for DNN 5.4 as I can see

Is there an updatet version of your "OtherSpiders.browser" File which covers more actual problems?

Thanks in advance
Regards
Gerald

Have just read this, and downloaded the file, hope it can reduce this problem for me. I also noticed many people on the DNN forum with the same problem, so I directed them here. ;-)

Thanks for the help.

The site does not go down when these exceptions are raised.

With the fix, I think some execptions have now gone away. However we're still getting 'VoilaBot' and 'twiceler' exceptions, but I don't feel too worried about them.

I have the same issue on our website, we see lot of pageload exceptions from crawlers websites.

One thing I am not sure is if the site goes down when the exception is raised. This happens very early hours that we cannot check.

Did this fix resolve the issue??
