Hello,
I have upgrade my site to DNN 7.3.2 and since this update some sites have problems with opening the Website Settings (Admin, Website settings) or the Page settings (Edit Page, Page Settings).

I get the following error: “An item with the same key has already been added”
• I have executed the script “to fix issues with HostSettings” (AdjustDNNHostSettings732.sql) See: http://dnnscript.codeplex.com/releases/view/132398.
• After this, I cleared the cache
• After this I recycled the application domain
But still I get this error. “An item with the same key has already been added”

After this I have check the “PortalSettings” table if there are any duplicate settings for this portal. All settings are unique.

The site as only one language, nl-nl.

Somebody any tips?

Hello Sebastian,

I as i try to describe, i have execute the script from that page: http://www.dnnsoftware.com/community-blog/cid/155044/fixing-portalsettings-issue-on-multilingual-websites-in-dnn-732

Also I have execute your script, that you have published on CodePlex, see: http://dnnscript.codeplex.com/releases/view/132398

Although I still have the same error.
(Also it look like I only have this error on one portal, all others works ok)

Do you have any more tips?

Thanks in advance 

Hello Sebastian,

Thanks for your support. I was unable to find any duplicates in the Portal Settings. Also I don't see misspelled names in Skins table.

Unfortunately, due time issue's I had to reinstall the website. (I made export for each page in the website, Installed a new website, and restored the exported pages).

After that the site was functioning without errors.

Kind regards,

Ronald
