| Major bugreport: My DNN portal crashes with a Runtime Error when I am logging is using an account with the Administrative security role in DNN.
I suspect the error is related to PageBlaster, based on the following stack trace:
Server Error in '/DNN' Application.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Did I configure something wrong, or do we have a bug on the loose? 
I am Using DNN 4.4, on a fairly clean installation, using a dedicated Windows 2003 server. The SQL server is on a separate server, and there are no other applications/software running on my portal server. It apperas that only accounts with the admin role assigned generate this error. The Host account works fine (when the portal has not been crashed that is), and regular user accounts also work like a charm.
I'll trust you with a MTSC connection to the server it if that helps you making the trace, or going over my config...? I can remove the IP range filter for the RDP connections, and create an Admin account on the server you can use.

Hi Jesper,
Do you have an asterisk specified for the cached-users attribute in the config? If so, change it to ".*" (period asterisk).
Then again if you have it working ok with regular users this may not be the problem.
Regardless, let me know what you have assigned for cached-users and cached-roles. | | | |

| I have the following in my excludePath section ...
In theory it should be the default file, with only one change taken from a forum thread here on Snapsis where you have a long debate with Nina regarding what to cache and what to exclude ...

Drats, mine didn't even show up all the way. < code > insert XML < / code >
and remove the spaces in the code tags | | | |

| Here we go :-)
<excludePaths><pathpattern="ctl=edit"excludeFrom="All"/><pathpattern="\?(?!tabid)"excludeFrom="All"/><pathpattern="rss"excludeFrom="All"/><pathpattern="\.asxh"excludeFrom="All"/><pathpattern="tabid.*?(46|73|90)"excludeFrom="All"/></excludePaths>
And btw, the settings for cached users and roles are both empty strings:
<br> cached-roles="" <br> cached-users=""<br>

| Somehow it is getting something in the cached-users, or cached-roles. Do you have a PageBlaster module on the page that is visible to Admins only? Try looking in the DesktopModules/Snapsis/PageBlaster/Config/PortalRules folder. If there are config files in there, look for one to have the cached-roles, or cached-users set. | | | |

| Ok, done.
The PageBlaster module actually *IS* present in admin-mode, since it has been added to all pages. I didnt figure that was a problem since authenticated+Host accounts work fine - but perhaps that is the cause of the problem?
I looked in "DesktopModules/Snapsis/PageBlaster..." folders and found the following:
* There appears to be a full version of the main config file in "DesktopModules/Snapsis/PageBlaster/Config/". The file differs slightly, as the exceptions from the file I sent you earlier are not present in it.
* There is a config file in the "C:\DotNetNuke\Website\DesktopModules\Snapsis\PageBlaster\Config\PortalRules" folder with the following content (replaced <> with []):
[node id="PortalRules" caption="Portal Rules" url="pb_showForm('PortalRulesForm')" ic="/DNN/DesktopModules/Snapsis/PageBlaster/nlstree/img/PortalRules.gif" exp="false" chk="false" cststyle="" xtra="false" target="_self" title="Portal Rules"] [/node]
Hope that helps.

| Btw, I can see there is an upgrade available from DNN 4.4 to DNN 4.4.1.
I have not yet upgraded, in case that is information you need.

| I am not a DNN expert or a .NET expert in any way, but could it be possible that the error is related to the following official bug mentioned in the DNN 4.4.1 changelog? I fit the description for getting the error ...
DNN-4463
http://support.dotnetnuke.com/issue/ViewIssue.aspx?id=4463
Perhaps that is the real cause of the error, and the PageBlaster code just gets stuck with the problem somehow?

| No, I don't think it is that last error logged in Gemini.
So you have the module assigned to all pages? There should not be any reason to do that. If you want a rule to apply throughout the portal then you just need to put it in the Portal Rules node of the configuration tree.
Think of the PageBlaster module as an extension of the PageSettings so that you can set the Cache and virtual path, etc. on each page separately.
Unless the config file in the DesktopModules/Snapsis/PageBlaster/Config/PortalRules folder has a number in the filename, then it is not being used.
The Snapsis.PageBlaster.config file in the DesktopModules/Snapsis/PageBlaster/Config folder is the default config file in case you need to revert to default. It is not used unless it is in the root folder of the website.

| Ok, i tried removing the module from all pages, and deleting it from the front page. That actually appears to have helped (i also restarted IIS just to be sure). The problem re-apperas if I add PageBlaster to the front page, even if it is only for that single page.
How should I apply the module? The installation document mentioned that the module has to be added to the pages (or at least 1 page). I kinda expected the front page to be cached?

| The only time you need to add it to a page is if you want to set the specific settings differently on that page than what is set in the main config file.
Like if you want a different Cache time, or you want to set a virtual path.
It should not fail on any page though. When you have it on the home page, go to Edit on the action menu so that you can see the config tree, then select Page Settings + Cache Settings and look to see if there is a value set for cached-roles or cached-users | | | |

| Mjeah ... only ... its 6:03 in the morning up here in the cold north, and I have to be at the office to meet a client at 10 ;-) So i'll continue my DN/PageBlaster work in approx 12 hours or so.

| I have removed the PageBlaster module from all pages (actually it was just originally on the front page, and then visible on all pages), but I still get the error on some pages. That is to say, I get the error on pages that do not have the module inserted. For that reason, I am pretty sure that there are no special settings (users, roles or otherwise) for the caching of those pages.
The error is now on a total of 3 pages. It is still only for users with administrative rights, but now includes the Host account. So I cant access/see the pages that have the error. The error message is the same as initially posted.
I have not changed any settings since the first post. But perhaps there is an error in my config files, or something?
Any thoughts or requests for more information?
:-)

| Hi Jesper,
It sure seems like something is sneaking into the config somewhere.
If you can get me access then I may be able to track it down.
Reply to the notification e-mail directly or contact me through my profile and lets see what we can do.

| More info: After cllearing *ALL* PagerBlaster caching files and restarting IIS the problem is gone. I don't know if it was just the TTL that ran out (my caching time is only set to 1 hour) or if it was actually deleting the files that helped. But currently I can not reproduce the problem.
On the pages generation the error there actually WAS PageBlaster modules inserted. This is possibly because I have changed settings in them, thus making local module registrations on those pages. As mentioned, I originally inserted on the front page and then enabled "Show on all pages". When I removed that option and deleted the module of the front page, PageBlaster was not removed from those specific 3 pages.
I only changed caching times though, so no user roles should be involved.
I have removed the modules from all 3 pages, and everything runs as it should now. But I am not sure I am ready to insert the modules back into pages, even if I wanted to change the cache settings on those pages. I am worried that I might not be able to access the pages later if the error returns...
