DNN 4.5.1 can't delete modules

Hi

Something very strange is happening in my DNN installation and don't know whether it is a bug or not.

It's happened with the standard DNN-blue skin and my own skin. Basically after a while I am no longer able to delete modules, and any call to action links don't seem to work the control panel just switches from edit mode to view mode.

Initially there were some errors I had found in the event viewer

and I wen't into the SQL 2005 database and there were 2 connections running, when I disconnected them the site started to work again but the same thing keeps on happening. Any ideas what this could be?

I've just been into the sql 2005 activity manager and tried to kill the connections I did before which got things working, but every time I kill them and go to my website they start up again and then none of the update links, delete modules etc works. This is the connections in the activity manager:

memschool_new.dbo.GetTabPermissionsByPortal;1

memschool_new.dbo.GetHostSettings;1

Any ideas why these are making my portal behave the way it is
(haven't been able to turn off the search engine scheduler as it won't let me)

thanks

Mark

No I'm not, thing is its not letting me change anything.

This is now currently the 2 active connections in SQL:

memschool_new.dbo.UpdateScheduleHistory;1

memschool_new.dbo.GetHostSettings;1

and the latest error in the event viewer is:

The strange thing about this is that it happened before so I re-installed dotnetnuke from scratch.

This is where I'm building the testsite: http://memoryschool.dnn3skins.com

You're right, it was a caching issue it just let me change my host settings:

Page State Persistence -  now, Page / (I had it set to Memory)
Module Caching Method - now Disk/ (I had it set to Memory)
Authenticated Cacheability - serverAndNoCache / (I had it set to server)

Don't know if that means there is a problem with any of those settings if you use them.

Should I turn my search engine scheduler back on or just leave it off and if so will I be able to use a search on my site?

Thanks for your help

Mark

Excellent, I'm glad you got it working.

I'm betting it was the Page Persistence.  I have seen that cause problems before.  Here are my recommended settings for DotNetNuke Perrformance Settings.

You could turn the indexer back on, but i think you will still get those errors. You could try clearing your index and starting over by using the procedure below.
