Thanks edde, I checked the above and it is already in place. I do remember trying to change something in single post and I was getting an error with line 68, so I got the original singlepost.php from the theme folder and pasted it into singlepost. This fixed the error I was getting with line 68. but then the sidebar started playing up.
When I go to a post address directly such as
https://www.muscle-milk-review.com/light-muscle-milk-review-youtube
there is no sidebar at all
When I go to the same page through the category link
https://www.muscle-milk-review.com/category/light-muscle-milk-reviews
I get the sidebar but with only categories.
I am still learning wordpress but I think Im about to give up on this one. Can anyone see what is going wrong here?
If I wanted to change theme, would it help, or just get the same problem?
