Google analytics link trackers with URLs that match this pattern:

domain.com/?utm_source=Text+Goes+Here

Causes a 404 error at the root level. Other levels seem OK.

We’ve tried adding question marks as acceptable characters in config.php:

$config['permitted_uri_chars'] = "a-z 0-9~%.:_\-?";

We’ve tried adjusting the Rewrite code as follows:

# Catch any Google campaigns directed to the home page
RewriteCond %{REQUEST_URI} ^/$
RewriteCond %{QUERY_STRING} ^(utm_source.*)
RewriteRule ^(.*)$ /index.php? [L,PT]

Also tried adding a question mark to this line in our rewrite code:

RewriteRule .* index.php?/$0 [NC]

I’ve seen some other threads with similar problems but no final resolution… any ideas?

We found the answer to this on this thread. That solution worked fine.

Hey ideadigital,

Awesome. Glad that you got this figured out.

If you need anything else, please just let me know by opening a new thread.

Cheers,
