Why can’t all hosting companies be like this.
I finally got round to doing my sites on Siteground. It was so easy FREE and quick. Obviously I then had to check the sites. If you are with Siteground you can do it yourself . They have a tool on cpanel
If you are with another hosting company contact them and find out what they are offering. If Siteground can do it FREE and so easily then maybe threatening to move to Siteground will make them do a free service.
The implications of not changing will mean any form will say it is not secure incl simple pages like”contact me”. Also Google will downgrade your ranking.
