Thanks for your patience and support guys.
I don't know since I changed them all

The one I remember was giving me issues this morning was one I had to change
www.xs400.com/forum/
Once I changed 'forum' to 'forums' it worked fine.
But I see that's one you have fixed now
I had that redirect setup before the site launched, but there are always cache issues when changing IPs or servers that can take a while to sort themselves out. The good news is the site is running on a faster and more secure server than the old site. The old software wouldn't even run on this server.
Looks very nice. The only problem I've encounterd so far is with the tapatalk app, can't connect to the servers and won't show any thread content.
I'm looking into implementing the tapatalk app again soon
Also only seems to search back to 2013 or 10 pages worth.
I'm working on tuning and improving the search. There are no date restrictions. Your results were only going so far back because the results were limited to 200. I increase the results from 200 to 500, so now you have 25 pages of results. If you need to sort through more than 500 results, you should be more specific with your search. When you're in a forum or thread, the quick search changes to show different options like "Display results as threads" or "Search this thread only". All of these can be set in the advanced search as well.
I may bring back the google search bar. For now in your browser address bar (or search bar) if you're using google as your default browser search engine, add site:xs400.com before the words you want to search for and you'll basically get the same results as the old google search bar.
I did just purchase Enhanced Search for Xenforo that will make the search even better. It will be faster and make a search for "tests" automatically match results for "test", "testing", and "tested".
I also decreased the minimum character count from 4 to 3 so you can search for words like oil.
