Description

In a multisite solution, cross-site links might get rendered incorrectly when sites have the same rootPath. The cause of the issue is ignoring the StartItem during site resolving. The issue occurs in solutions that use cumulative hotfixes released before February 2023.

For example, for two custom site definitions, where "/sitecore/content" is the rootPath, and "/StartItem1" and "/StartItem2" are StartItems for the first and the second sites, the expected result is:

https://site1.local/Link
https://site2.local/Link

The actual result is:

https://site1.local/Link
https://site2.local/StartItem2/Link

Solution

To resolve the issue, consider the following options:

• Upgrade your solution to Sitecore 10.3.1 or later.
• For Sitecore 10.3: download and install the latest cumulative hotfix available in KB1002844
• For Sitecore 10.2:
  • Upgrade your solution to Sitecore 10.2.1 or later
  • Download and install the latest cumulative hotfix available in KB1001439
