I think there is a problem with DNN5.4.1 when upgrading websites which do not use "en-US"..(Some of us don't)

Below is a log of what's happening and how I solved it.....

-------------------------------------------------------------------------

Upgrade website from 4.9.2.

unzip DNN 5.4.1 upgrade onto website.

00:00:20.625 -   Executing Application Upgrades: 05.03.00 Error!

00:00:23.687 - Installing Optional Modules:

00:00:25.218 -   Installing Package File Messaging_01.01.00_Install:  Error!
00:00:25.375 -   Installing Package File Taxonomy_01.01.00_Install:  Error!



05.03.00.log is empty.

---------------------------

On starting the site:

An error has occurred.
DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Framework.DefaultPage.InitializePage() at DotNetNuke.Framework.DefaultPage.Page_Init(Object sender, EventArgs e) at System.Web.UI.Control.OnInit(EventArgs e) at System.Web.UI.Page.OnInit(EventArgs e) at DotNetNuke.Framework.PageBase.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---



At this point I could not find a way to fix it so I Restored the website back to DNN4.9.2,

upgraded to DNN5.2.3.   Everything is OK and website running without issue.

Upgrade to DNN5.3.1   Everything is OK and website running without issue.

Upgrade to DNN5.4.1   Nothing works!!!!

An error has occurred.
DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Framework.DefaultPage.InitializePage() at DotNetNuke.Framework.DefaultPage.Page_Init(Object sender, EventArgs e) at System.Web.UI.Control.OnInit(EventArgs e) at System.Web.UI.Page.OnInit(EventArgs e) at DotNetNuke.Framework.PageBase.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---


----------------------------------

Restored the website back to DNN4.9.2

Upgrade to DNN5.3.1   Everything is OK and website running without issue.

Installed rebuild French Core Langugae pack from Fresh installation of DNN5.4.0. (Had to rebuild the core langauge pack because the Language pack for DNN5.x did not work.)


Upgrade to DNN5.4.1  French langauge works OK.

English (en-GB) does not work..

     An error has occurred.

Hi Alex,

Sorry I didn;t see that thread.  But the problem I was trying to highlight wasn't especially the install, but the fact the DNN5.4.1 does not seem backward compatible with the previous core language pack.  Therefore any attempt to upgrade a website not runnig en-US will fail, and the website will not be available.

You can re-create this simply, create an installation of DNN5.3 and load in a core language pack, turn that to the default langauge and turn off en-US.  Try the upgrade and your then in trouble!!.

Indeed, you don;t even have to turn off the en-US, just switching to a lanague with an old langauge pack (French one 5.x fpor example) will stop the site from working.  You then have to get rid of your langauge cookie to get it back into en-US, which does work!

Regards,

Dave.
