Terrorelfe – make those edits to the plugin and it functions properly. As far as I am concerned it is resolved – the plugin just needs to be updated now. Its a simple edit to fix what you have for now. I am sure the author will make these changes in the next release. Please consider how much you are paying for the software and understand why fixes aren’t released immediately. This is a labor of love for the author, not an attempt to make money. The solution was posted, so lets give the guy a little credit and breathing room. Thanks for the great plugin!
//global $wp_rewrite;
//$old_base = $wp_rewrite->get_tag_permastruct();
//$old_base = str_replace( '%post_tag%', '(.+)', $old_base );
//$old_base = trim($old_base, '/');
//$tag_rewrite[$old_base.'$'] = 'index.php?tag_redirect=$matches[1]';
I’ve released a new update (v1.2.3) to WP-No-Tag-Base that fixes the issue many sites were experiencing with redirect errors and old tag bases not 301 redirecting. Remember to clear your DNS cache while and to refresh your WP permalinks manually (settings > permalinks) while debugging. If you have anymore issues please jump over to my site and use the comments form or contact me so we can work through them!
@nextusbroadcast – Thanks for the kind words. You hit the nail on the head, it’s a labor of love.
