I am admin for a Danish board, dfac.dk/fritforum. I have a serious, probably self inflicted, problem with brocken, internal links in posts that I hope there is a simple solution for.
Until recently we ran our forrum as a subdomain ie. fritforum.dfac.dk. I have upgraded to php 7.0, phpbb 3.2 and implemented SSL. To get SSL to work, i found it necessary to change the main link to
https://dfac.dk/fritforum and by adding a redirect to .htaccess I got all variations of fritforum.dfac.dk and dfac.dk/fritforum to work as the main URL. So far so good.
Now I have found a problem that I think I know the reason for, but I can´t find a quick fix. All internal links in posts are brocken and just lead to the boards home page. I think the reason is, that when people post and want to link to some other post on the board, they just type or copy the URL without using the link bbcode. Alle internal links to uploaded dokuments, pictures and so on, have automatically been changed, but the direct links in posts have not been, and the redirect obviously doesn´t solve this. So now I have almost 16000 posts with potentially brocken links. HELP please.
