I consistently get the exception below in Firefox browsers. it seems related to the web analytics module. It happens on all pages, but not on other sites on the same application instance. The exception stops occuring when I disable the option Track browser types.

I am getting the exact same error in v5.5.3789, but with the Google analitycs webpart added on the masterpage. As there is no option for the Track browser types in this webpart, i am unable to use this webpart at the moment. The only option selected in the webpart is the Multiple top-level domains.

Hello,

1. Is it related to Firefox, too?

2. What version of Firefox do you use?

3. What is the related event log in Site manager -> Administration -> Event log?

4. What version of .NET do you use?

Thank you in advance for your reply.

Best regards,
Helena Grulichova

Hello,

1. we would need the full text of error message you get (the stack trace)

2. did you switch off the web analytics module for testing purpose? We would need to know if the issue is related to Google analytics web part or it is the same problem with web analytics as Michiel described.

Thank you in advance for your reply.

Best regards,

Hi all,

We have further information about this error.
This has been recently discovered as a bug and has been fixed in 5.5.9 Hotfix release.
I'm very sorry for the inconvenience it has brought to you.

The problem was in detection of the browser version. The code for that has been rewritten.
To solve this issue, please apply at least this hotfix version, preferably the latest one available.

Thank you for your understanding.

Best regards
Zdenek C.
