Cannot access a page after upgrading to 4.2 (Specified argum

Hi there,

After Upgrading my website to 4.2 I have been having an issue with my homepage. I can view it in the browser no problem, and even edit the page while browsing the site. But when I try to go into edit the content directly from sitefinity I get the following error:

Specified argument was out of the range of valid values.
Parameter name: index

[ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Hello Jamie,

This is strange indeed. I suppose something went wrong during the upgrade. One solution is to send us your database and configuration files so we could reproduce the issue locally.

Otherwise you could try deleting and recreating the home page if it is the only page that is causing problems.

Hello Lubomir,

I had this issue several times now. The recreating the page is fixing the issue but this is not good experience for the end user managing the site. Can you please let me know if there are specific sections I can check to fix when having such a problems? As it will not be convenient to send a DB backup each time when pages are bringing "Specified argument was out of the range of valid values".

Thanks,
Armen

Hi Armen,

Unfortunately I don't see how we can find a solution for this problem if we do not have the database and the configuration files locally, so we could reproduce the environment and see what is wrong. You can check your upgrade log to see if there weren't any errors during the upgrade process. Also check if your modules have the same version in SystemConfig.config - if they don't that means that some of them weren't upgraded properly.

Hi Lubomir,

This is starting to repeat for us, not sure why. May be that is because we are using NLB? Not sure.

Basically deleting and recreating the page is solving the issue but it is starting to happen again on some page. I would delete it and create once again but I have another problem coming after that. Some other pages have links to that page, and I am interested when deleting some page, can I know which pages have link to that page that I delete so that after I can go and try to fix those links.
We have more than 500 pages and it is hard to go over all pages to verify broken links and reason after.

Thanks,
Armen

Hi Armen,

When you delete a page with additional URLs these additional URLs are deleted as well. So you can recreate the page with the same additional URLs the links to this page should be good. Unfortunately
there is no way to detect broken links, as you can have custom or user controls, whose content we cannot examine.

Hi Lubomir,

Thank you for your answer.

I agree with URLs but it also contains sfref="[pages]fcca4b4a-722a-4daa-a0c5-c081829aefca" parameter. Which I believe will be not valid after that. Can we just ignore that?

Regarding links I was mostly interested within your native content, not the custom controls built by us. Like if we are deleting some page it will be very helpful to know which pages will have broken links.

Thanks,
Armen

Hi Armen,

Yes, the sfref attributes point to page GUIDs that will be different after you delete and recreate the page. Basically our parser would check the GUID and generate a proper link to the page, if the GUID exists. Otherwise there would be no link.

Unfortunately we do not have an out of the box tool, or even API methods, that would verify the content of News items, Generic contents, etc. for broken links.
