A client of mine has Sitefinity. His hosting provider has upgraded .NET to 4.7 and now he has the famous error:
An item with the same key has already been added.
This link (knowledgebase.progress.com/.../sitefinity-and-net-4-7-compatibility-issues) shows in which versions this bug has been fixed. However when I login and see my licenses screen, we can only download the following versions:
Does this mean that we have to pay for a new license just so we can fix this error?
That way I can indeed download the fixed version. However, my license files doesn't work in that version.
Have you opened a ticket with support?
I can't promise anything, but I usually do that when I do not get a response on the forums and it generally gets some kind of reply.
@Brian: I can't open tickets. The system tells me that I have to buy a new license to get support.
@Victor: Each license file that I download says that the license file is invalid (see screenshot for available licenses)
I am not sure about the exact version. It was 6.x I think.
I can upgrade to 7.2.5310 but that doesn't fix the problem, since the error will be also raised in that version.
To make things easier, please try to do the following:
1) In telerik portal download Sitefinity Internal Build 7.2.5331.0
2) Download license from portal for version 7.2.XXXX
3) Upgrade your project with this instruction: docs.sitefinity.com/upgrade
4) Activate upgraded project with license downloaded from step 2
The version is: 6.1.4700
My license allows me to download and upgrade to 7.2 5320, however the bug is still present in that version.
