I also need to create a clean tag url, but when I try the rule below, it doesn’t work because of the previous rule (probably), how can I fix this issue?
BOTH RewriteRules should NOT have the optional trailing slash as that would suggest to the server that the visitor is requesting a directory. Worse, relative links don’t know which directory level they’re supposed to retrieve internally linked files from. Test your code using the trailing / as well as without and you’ll see the problem (missing support files).
