Split-Post not working on pages

Hi First post so please be gentle with me 🙂 Installed wordpress, all working fine, superb system and very easy to use. And whoever developed drag and drop pictures is a genius! Anyway I digress.

I’ve been using the split-post functionality on both posts AND pages. Now it only works on posts. I’ve no idea if I’ve changed anything but it generates the same HTML

<p style=”text-align: justify” class=”MsoNormal”><!–more–>

I’ve checked it’s the same in both pages and posts and it is. It used to work on the pages and stopped for some reason. I’ve done so much buggering about, who the hell knows? But I’ve cleared the cache, tried two different browsers and two different machines and the problem remains.

Any ideas? Thanks Alex
