And then a few weeks go by before you finally get around to repeating the instructions and trying to perform the activity... and you've completely forgotten how to do the simplest part of the process.
How To Log In To Your WordPress Website or Blog.
So, here it is - in words of one syllable for the two therapists who 'fessed up today...
In the search bar at the top of the page enter:
Name of your website or blog/wp-admin
For example, I would put in www.lollipoplocal.co.uk/wp-admin
This will bring you to the log-in page where you can input your details.
... and if you've forgotten your Username and Password too, just click on 'Lost Your Password' and put in the email address against which the site was registered and WordPress will send you instructions on how to create a new password that you can make a note of and put in a safe place.
Remember, when choosing a WordPress username, it is never wise to go with the default 'admin' as hackers work on the basis that this is the username and so it makes the job of cracking the password half as difficult.
