OK. I’ve deactivated, logged out, logged back in then reactivated. I then set up the ‘Like Box’ widget at the top of the Primary Side Bar. Then I added a Text box immediately below this and inserted the Code for ‘Follow’. I saved both.
I then went to ‘Visit Site’ and it showed both buttons and images where they were supposed to be. I went back into Widgets and moved the ‘Like Box’ widget to the bottom of the Primary Side Bar. I went back to ‘Visit Site’ and the Follow button was at the top and the Like button was at the bottom of the Primary Side Bar as I had wanted.
BUT I then logged out of Word Press, checked the site through Firefox and it was back to the same blank spaces! My partner’s just checked the site on his tablet and it’s showing blank spaces too.
So, it seems that logging out of Word Press seems to be the issue here. As soon as I do that, it seems to deactivate the programme.
Of course that doesn’t explain how you can see the buttons.
One final thing; I just moved the Like Box widget back to the top of Primary Side bar and went to ‘Visit Site’. It flashed up a message indicating that it was loading – but then it just went blank again!
Don’t know how much of this helps but fingers crossed!
