I have increased httpRuntime
I have no 3rd party modules
There are over 400 pages with content using DNN Pro HTML and Links modules.

Also I have checked the database Users & Portal tables:
> Portals Table: AdministratorId = 2 and AdministratorRoleId = 1
> Users Table: userID = AdministratorID = 2 AdministratorRoleID = 0 (originall was changed to 1)

Which version of DotNetNuke are you using?

Since you are using the Professional edition, you are entitled to tech support from DotNetNuke Corp. You might also want to open a ticket with them.

Of course I have already opened a help desk ticket with them. I just have found you so helpful and wanted to pose the issue here as a paying member. We are using 6.1.1 for this installation.

I wasn't trying to brush you off. Just trying to make sure you get all possible help!

I'm not aware of problems creating portal templates with 6.1.1.

As a test, try creating the template WITHOUT including content. That should be much faster.

If that works, then runtime might be the problem. To which value did you increase it? Try increasing by a factor of 10 and see if that makes a difference.

No worries. I will try the "no content" method to see if size is the culprit. Here is the current web.config settings:

httpRuntime useFullyQualifiedRedirectUrl="true" executionTimeout="3600" maxRequestLength="118192" requestLengthDiskThreshold="118192" requestValidationMode="2.0"

I was also thinking of cloning the site and upgrading it to 6.2.2 and give it try.

For fun, set executionTimeout to 100000 and try it.

I attemped to export a template w/o checking the content box. I received the same error as described above.

Okay for fun... I updated execution in web.config - restarted the site and app pool. Exported w/o content - same error.
Exported w/ content - same error.

Can you look in the Event Log and see if there are errors reported?

Back from vacation and onto this issue: I just tried to create a new template and this is the result from the event viewer.

I'm wondering if perhaps there is something "wrong" with the portal that is causing the problem.

I just exported two portals (one small and one fairly large) from my test installation that is DotNetNuke 1.1.5. No problems with either, though the large one took more than a few minutes.

Do you have a second, small portal that you can try?

Did you ever get help from DotNetNuke?

LeAnne,

Were you able to resolve this issue? I am struggling with the same problem and tried all the options mentioned in this post but no luck. Please let me know how you were able to get around this.

Many thanks

John,

What happens when you try to export a template? (and which version of DotNetNuke are you using?)

This might help. I found this forum string while confronting the same issue. I seem to have gotten past it by going to host settings and restarting the application and then trying again to create the site template. This time it worked without errors.
