I am having an issue when trying to add multiple tags to URLs on my site.
Using a + in the URL works fine
but if I add a comma to make the search inclusive
then I generate a 403 permission error.
You don't have permission to access /tag=15mm,sci-fi/ on this server.
It shows the same issue if I use the ?tag= format for the URL as well.
I don't have anything in my .htaccess file that appears to be modifying the URLs with tag in it
Anyone have an idea why the comma in the URL is a problem?
