I have a funny bug going on with a particular post. As soon as I tag it, it makes the post immediately prior to it disappear from my Homepage so visitors can't see it. When I remove the tags from the post, the prior one makes a reappearance.
I can't see anything unusual in the post HTML code - and have even re-written the post from scratch and re-published it to try and get around the issue but no luck. Same thing again.
Does anyone know what might be causing this to happen? All other posts appear to be fine, it is just this one post that's causing a problem.
Need answers that aren't overly technical as I am not super-code savvy.
Many, many thanks
