Swtiched from VB5 to VB4. Now I have 90k not found 404 errors
Just like the title says. I upgraded to VB5 as I was receiving email on the version I had that it had security flaws. I had already paid for the upgrade to 5 so I figured why not. Made the change and had performance issues, template complaints from users, and really a limited number of skins to choose from. Tried to make it work for about a month but I got nothing but negative feedback and a kept running into issues trying to get the site up to bar. I decided to drop back into VB4 again.
When I made the switch to 5 it updated all of our links to SEO friendly ones. When I switched back so did the links. Since then the number of not found 404 errors on google webmaster have sky rocketed. I contacted the support forum on Google webmaster and he recommended creating 301 redirects. He said there was a way to "script" it and save myself time. When investigating further he said it would be best to contact someone at Vbulletin. So here I am.
The site is www.killbillet.com. It is PHP based. It is currently on Version 4.2.3.
This is definitely outside of my expertise so I will likely have a few questions but I learn quickly. Thanks in advance and let me know if you need any more information.
