DNN Version: 4.5.5 (Multilanguage), DMX Version: 4

Error-Message:

A critical error has occurred.
Object reference not set to an instance of an object.

Effect Description:

When we have language set o EN and display a site with the module the Module is displayed fine without problem. We let the Language on EN and navigate to other site in in our protal with a other DMX-Module all is ok.

But

When we set the lanuage to de-DE the Error is displayed, we refresh the page but the eror is displayed. We set the language to EN and refresh the page but the error is also display but in EN language. So now we have set the Language to EN and have the error in englisch on the page now we navigate to other page in our portal with a dmx module and see the Module is now displayed right.

Compression:

We have for a Test disabled the Pageblaster-Module for the compression and remarkt in the web.config but we have the same effect.

Test:

You can see the effect on our website under http://www.it-power.biz we have on our page Downloads and under Support/Documents placed a DMX 4 Module.

Any Idea whats wrong here!?!?!?

Thank You

Have you used DMX3 before DMX4?

When yes you must remove the DMX-Modules from pages before Update to DMX4! Now when this is yes you must delete the page and create a new and place the new DMX4 Module on this new page.

Hope this Help!

 

Hi,

I'm not aware that you have to remove module instances from your site. The only ones that would break are the Shortlist, Navigator (add-ons) and the one that you've set to start with something else than the default (you can just switch the setting back to default before upgrading). You'd use the latter on the 'search results' page for instance. Regular DMX instances should not throw any errors. I'm eager to hear from anyone that experiences that. Let me know.

@Jack: did you use any add-ons with DMX 3? Did you manage to see the module before it threw an error?

Peter

This was an "upgrade" in the sense that DMX 3 "was" installed. But I uninstalled everythig about DMX 3 before I installed 4 for testing.

And no, I never did see the module, inserting it on a page produced the error.

You're on SQL 2005?
