Thank you, I really like RealFaviconGenerator!
The above solution did not help me but this one did:
In .htaccess file section # SPECIFIC EXPLOITS
I replaced
RedirectMatch 403 config\.
with
RedirectMatch 403 (?<!browser)config\.
and in section # 5G:[REQUEST STRINGS]
replaced
RedirectMatch 403 (eval\(|\_vti\_|\(null\)|echo.*kae|config\.xml)
with
RedirectMatch 403 (eval\(|\_vti\_|\(null\)|echo.*kae|(?<!browser)config\.xml)
