Hi Kongondo,
Thanks for getting back to me.
I think I have it sorted, though I took the sledgehammer approach and clean installed both PW and PB.
Previously there were no blog templates installed in /site/templates, they were all in /site/modules/ProcessBlog/template-files... this time around they are all in /site/templates and at least I now get pages when I try loading /blog and so on... i.e. no longer getting a 404.
Couple of questions... the blog templates all include blog-main.inc.
My current setup uses prepend and append files, so I'm guessing that to get it working well I'll have to create a blog-main.php as an append file, based on a merger of current _main.php and the blog-main.inc... that is if all pages are to work off a consistent model...
Initially the blog pages stacked everything vertically, but I've copied 'css' and 'js' folders from the module folder to /site/templates and its producing a more expected layout... except that it mixes the layouts/contents of blog-main.inc with that of the _init.php and _main.php currently being pre/appended, but I think that will be straightforward to clean up.
Still don't know exactly what happened previously, unless an install issue with folder permissions causing some things to not be placed where they should be. That's my current best guess, although there were no on-screen error messages to indicate that... I suspect that the /site folder and its children were not writable to the extent needed.
Anyway, atlas I have something now, which is a giant step forward from yesterday, and a base on which to learn more.
Cheers
Rob
