For large-scale archives, the PHP or .htaccess fix alone may not be sufficient. Links may be stored incorrectly inside posts or in search engine indexes.
/archive/index.php/t-123.html → /new-forum/threads/123/
The good news is that there is a solution to this problem. The Topic Links 2.2 archive fix involves updating the plugin's code to correctly handle archived topics. This fix ensures that when topics are archived, they are properly redirected to a new location, and that links to these topics remain intact.
Topic Links 2.2 Archive Fix is a targeted update designed to resolve critical link-handling errors within archived content. Users previously reported issues where legacy forum or topic links became broken or misdirected after being moved to an archive state, and this fix serves to restore that connectivity.

The root of the problem lies in a mismatch between the legacy URL slugging system and the new routing engine introduced in version 2.2. Specifically, the archive controller fails to append the correct directory prefix to threads moved into the long-term storage tables. This results in the system searching for active thread IDs in the archive directory, leading to a total failure of the link-mapping process.
