Server Error in '/' Application while Saving Site Settings

Hi Joe,

I have just updated to version 2.3.7.6 all installations hosted on my server (and several hosted by providers) and noticed that for two of them I get an error when saving the site settings (even without changing any data).

Any ideas about what I can check/fix to overcome the issue ?

This is the error form mojoPortal System Log:

Re: Server Error in '/' Application while Saving Site Settings

Hi Diego,

This is actually the result of a change from a recent ASP.NET security update. It happens because you have a lot of roles and with the checkboxlists for all the permissions under the permissions tab combinned with all the other form elements it adds up to more than 1000 form elements. The ASP.NET security update set a limit of 1000 and this error happens if there are more than 1000.

I've already fixed this in our source code repository by moving the permissions out of site settings into separate pages to reduce the number of form elements. I will make a new release  very soon with this change, but there is an immediate workaround you can use until then. You can put this in user.config

<add key="aspnet:MaxHttpCollectionKeys" value="1500"/>

you may need to experiment with the number depending on how many roles you have, maybe try 2000, and then reduce it as low as possible until the error returns and then put it a little higher so the error does not happen.

You might also review your roles and if you have some that are no longer used remove them.

Best,

Joe

Re: Server Error in '/' Application while Saving Site Settings

Thanks!!!

It works just with 1500.

That also explains the erraic error we got from another custom module.

I will use the suggested workaround when needed until the new release is available.

Best Regards!

Re: Server Error in '/' Application while Saving Site Settings

Hi Diego,

I would still reduce it as much as possible, the default is 1000 so it will have to be a number higher than that, but if 1100 works I'd use 1100 instead of 1500. 

Best,

Joe

Re: Server Error in '/' Application while Saving Site Settings

Thanks for this... it solved the same issue for me.  I was able to get away with 1100, no problem.

  <add key="aspnet:MaxHttpCollectionKeys" value="1100"/>

Re: Server Error in '/' Application while Saving Site Settings

Hi,

Is it a custom feature?

How many settings does the feature have?

How many roles do you have?

I think you will have to increase the number until the error stops happening. 

Hope that helps,

Joe

Re: Server Error in '/' Application while Saving Site Settings

Hi Joe, unfortunately we just came across another area of the system that is impacted big time by this ASP.NET update: The Content Manager publishing page. My webmaster brought me this same error--she was getting it when trying to publish a content instance to a page (error happens as soon as she hits the green + icon).

I was able to get Publish to work for our site by setting aspnet:MaxHttpCollectionKeys to 3000 (2,500 still didn't work).

For reference, we have 942 items in mp_pagemodules for the site. It seems that to work around the issue with this page, aspnet:MaxHttpCollectionKeys needs to be set to higher than three times the number of pagemodules for a site, so any site with more than 333 modules would be affected.

Thanks,
Jamie

Re: Server Error in '/' Application while Saving Site Settings

Hi Jamie,

Thanks for letting me know, I'll look into a fix for this. However, I think it is based on the total number of pages not pagemodules because on that page one module is represented and the rows are per page, pagemodules only represent the rows that are published.

Best,

Joe

Re: Server Error in '/' Application while Saving Site Settings

Thanks Joe. If it helps your testing, we have 777 pages in the affected site right now.

Re: Server Error in '/' Application while Saving Site Settings

Hi Jamie,

After looking into it I realized it doesn't correspond exactly to the number of items because its the hidden viewstate fields (required to support grid events) that start to add up in addition to the actual form elements needed for each row such as the image button per page row. The number of viewstate fields can be affected by configuration on the <pages maxPageStateFieldLength="100" 

We use a small size (100) mainly because some mobile browsers will ignore hidden fields if they are very large, but we probably could go higher than 100 if needed to reduce the number of hidden fields.

I've got a solution for it already in my branch in the repository that should be in the default branch in the next day or so. Basically if the number of pages is higher than a config setting (default is 150) it will change the functionality such that when you click the button it opens a dialog page instead of going into edit mode of the grid. That way there is no change for small sites.

Best,

Joe
