I installed Links 6.2.3 on DNN 7.2.2 and if I link to a URL or Page I have no issues but linking to a file onsite it returns this error:

Error: Links is currently unavailable.

Do you have the same issue if you create a link to a file in the HTML module editor and specify that the link be a relative or absolute secured url which will also use the LinkClick handler?

Also, on a hunch that I have as to the cause of the issue, please check the site's web.config to see if the following section is present:

<cryptography defaultProvider="CoreCryptographyProvider">

      <providers>

        <clear />

        <add name="CoreCryptographyProvider" type="DotNetNuke.Services.Cryptography.CoreCryptographyProvider, DotNetNuke" providerPath="~\Providers\CryptographyProviders\CoreCryptographyProvider\" />

      </providers>

    </cryptography>

Thank you for responding.

If I use an HTML module to create links to files on the site there is not issues. The issue only happens in the Links module.

I looked in the web.config file for the code and found none. Where should it be inserted?

Thanks

I'm surprised that the test of creating a secure link to a site file in the HTML editor did not produce a similar error but provided that you are sure that the DNN installation is running version 7.2.2 (or 7.2.1), the cryptography sections introduced in v 7.2.1 should have been automatically merged into web.config during an upgrade from an earlier version or on a new install of 7.2.1 or 7.2.2.

If you have superuser (host) access to the website you can use the Host --> Configuration Manager to merge these changes into the existing web.config file:

1. Verify that the site's root folder has been granted full file system permissions (including modify) for the ASP.Net worker process account (IIS Identity account) and that the web.config file is not marked as read-only.

2. Locate the file 07.02.01.config in either the site's Install/Config/ folder or in the same folder of a newly downloaded and extracted DNN 07.02.01 or 07.02.01 install or update package. Place the file on your local computer were you can easily find it during the next step.

3. Open the Host --> Configuration Manager and select the Merge Scripts tab.

4. Click on the Select File button and select the 07.02.01.config file residing on your local computer.

5. Click on the Upload button. The merge script for the cryptography sections will appear in the editing window.

6. Without making any changes to the merge script, click the Execute Script button.

7. The changes should be merged into web.config and the site's application pool will take 20-30 seconds to recycle.

8. Test to see if this has resolved the issue. Most likely you will need to recreate the links.
