There is one more point, the profile page opens at two addresses:

• /page/view-persons-profile?id=1
• /page/view-persons-profile?profile_id=1

It turns out that one page has two valid addresses. If optimized links for search engines are enabled, then redirection occurs only if you follow a link like: /page/view-persons-profile?id=1. If you follow a link like: /page/view-persons-profile?profile_id=1, then the redirection to the optimized link does not occur.
