Apologies for this, but it was not intentional – as a result I have just unearthed a bug in my bespoke WordPress code. I haven’t fixed it, but knowing it is there should prevent this happening again.
In WordPress, you can either edit in HTML mode or in Visual mode, the latter shows the editing page as it would appear when posted, complete with images. I almost always use the HTML mode, as it is quicker to use, and makes more sense to me. However, I do switch into Visual if I want to change an image size.
This is what I did yesterday, I edited and posted from HTML mode, complete with an lj-cut before the picture. I then thought the picture too big, went into edit mode, and switched to Visual to change the image size.
It seems that doing so loses the “lj-cut” tag from the posting, probably because it is a bespoke tag and no understood by the Visual mode parser.
I’ll keep an eye open for this in the future, so hopefully it won’t happen again.
