here is the solution
In your htaccess you need to add a B flag to the last line, like this:
RewriteRule ^.*$ index.php?qa-rewrite=$0&%{QUERY_STRING} [B,L]
It’s due to some changes with the urlencode function. For some reason this didn’t get updated in the htaccess-example on the bugfix branch, only the dev branch.
Thanks a lot Scott, I toke the solution from here
