FilterProvider syntax has changed in Apache 2.4(Error FilterProvider takes three arguments, filter-name provider-name match-expression)

With apache 2.4 there has been few configuration changes in place and causing 500 errors. One such is the legacy filter_module syntax on the htaccess file.

Error : The following error in error log is actually causing by legacy filter_module syntax on the htaccess file.

[Fri Jan 03 00:19:57.673915 2014] [core:alert] [pid 774253] [client X.X.X.X:54553] /home/XX/public_html/.htaccess: FilterProvider takes three arguments, filter-name provider-name match-expression

With apache version 2.4 in your server  it wont accept the legacy filter_module syntax. You should need to make some changes in it. For example my users filter_module rules were as follows in his .htaccess file.
