I suggest to try the Redirect or rules module.
You can create URL redirects manually for each of these pages, but the Redirect module makes this much easier.
- Go to "Configuration > Search and metadata > URL redirects > Fix 404 pages" (
So, you can see that there are a few paths that I have tried to access that do not exist. Next, to each one there is an "Add redirect" operation.
When Clicking on "Add redirect" link we can specify where we would like users to be redirected when they reach the page that does not exist.
