sendy 404 error htaccess php
I purchased Sendy today
and installed it following this guide https://www.wpmaximum.com/install-sendy-on-digitalocean/
I installed it with digital ocean on this domain: emailsversturen.jajomedia.nl
But now if I go to emailsversturen.jajomedia.nl I get a 404 error
It only works if I put emailsversturen.jajomedia.nl.php
But than every time If have to put php after every new page I go to.
I changed the .htaccess but it didn't work
I also changed ensure AllowOverride Non to AllowOverride All
But still it doesn't work.
I am I doing something wrong?
