My problem was resolved by changing this:
go into your admin panel
go to plugins
choose FS contact form
click on the advanced tab
find: Enable an HTML anchor tag on the form POST URL.
and UNCHECK it
your form will now redirect to your page and not to the form
I changed my site language to dutch but the subscribe text still says ‘Subscribe to blog via e-mail’.. Is there something else I should change to get it to be displayed in dutch?
