I've been using PhpBBSEO Advanced url rewriting for a number of years now and have thousands of threads indexed in google but we moved it to a new server last week (domain has not changed) and I had to redo the phpbbseo settings in the ACP and regenerate a new .htaccess and now Google seems to be replacing our existing links with links that have urls with "html?style=18" appended to the end of the urls and those links go to an error "style data can not be found". My default style is Absolution which WAS style 18 in the database on the old installation on the old server but on the new one it is style 21 (not sure why. I guess because when I migrated I deactivated all styles except prosilver and then re-activated the styles once on the new server-perhaps in a different order?)
If I type in 21 in place of the 18 in the url the link works but why would that "?style=18" be in the indexed urls anyway? I don't have any bot-accessible styleswitcher or anything like that other than the built-in one in the UCP Board preferences for logged-in users. I tried changing the style number of Absolution to 18 in the pphpbb_styles table in the database but that makes all the internal links go to the "style data can not be found" error so I changed it back.
Is there anything I can do to a) make the current links in Google work? and/or..... b) get google to re-index everything without the "?style=18" part?
