I've download 5.1, but thanks for looking into the position of the back button for the next release.
Thanks also for the link regarding blog images, I'll read this and will follow your instructions above.
I defined the area for the Pulse Blog in Blocs, but have been writing the articles via the Pulse CMS Dashboard. I've now discovered what the issue is. The heading on the click-through blog page is picking-up a type style which is white. That's why I can't see it on a white background. I'll look into how I can fix this through CSS.
After today's success of downloading Pulse 5.1, updating Blocs to 2.6, exporting my site as a Pulse 5 theme, doing a fresh install of Pulse 5.1, white labelling it, and then adding in my Blocs site, everything now works perfectly. From here on in it's more about fine tuning. So I'm a very happy chap this evening!
Thanks, as always, for your assistance.
