Having watched your wordpress essentials video on installing wordpress I used the 1 click install (Softaculous) via my hosting service namesco.co.uk. I received a “worpdress installed successfully” e-mail but when I click on my registered domain on the e-mail it takes me to a namesco holding page – not a wordpress page as shown in your video. Am I missing something?
Is your domain name registered with another company? (i.e not namesco?). If it is registered with another company then you will need to change the domain name nameservers in your domain name control panel. Namesco will tell you what these need to be change to.
