Hi there,

thank god this is a new installation that's not productive, yet...

I have just installed a plain new 4.6.0, without much special stuff on it. Went through the host-configuration and switched on Whitespace-filter compression... and - boom - get an exception and cannot access the portal anymore. Not cool :-(

The exception code:

 

[NullReferenceException: Object reference not set to an instance of an object.]
   DotNetNuke.HttpModules.Compression.WhitespaceFilter.Write(Byte[] buf, Int32 offset, Int32 count) +104
   System.Web.HttpWriter.Filter(Boolean finalFiltering) +251
   System.Web.HttpResponse.FilterOutput() +85
   System.Web.CallFilterExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +46
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64

 

Anybody with some quick help on this? I could access the database if I have to (I'm admin on the system and have the SQL Server Management console installed)...

I would also consider this a bug...

Kind regards,

Jashan

Ok, that wasn't too hard to fix: Table HostSettings, look for WhitespaceFilter, change Y to N (kind of surprises me, though, that people store booleans with Y/N instead of 0/1)...

One thing to be very attentive to, though: When you Attach and Detach a SQL Server Express Database with SQL Management Console, it seems to remove all security permissions on the NTFS level. So, before you restart DotNetNuke make sure you re-add permissions to the database files for IIS_WPG or ASPNET (depending on whether you're on W2K3 server or WinXP). Can this somehow be changed to not happen? I remember sweating a little bit when I couldn't restart DNN after doing some "offline-SQL-operations" and not being able to reconnect to the database... took a while until I found out it was the NTFS file permissions back then...

I've also read somewhere in the forums that the broken Whitespace-filter is a known issue (maybe only under certain circumstances?), so I won't bother filing a bug-report... Looking forward to see 4.6.1 ;-)

Btw: I love DNN, keep up the good work. This is really quite an amazing system you have created, and I love seeing the quick progress being made... Especially the AJAX integration is something I really enjoy! ... and it's always wise to wait a little while before updating production systems to the most current version ;-)
