I wonder if this was so simple!
I was using the plugin Page Links To, some time back, but although its purpose had gone it was still sitting there active and I decided it was time to get rid of it.
The front static page was set to the Page named Dummy which used Page Links to, to redirect to Home.
I deactivated and then later deleted after this didn't work the Page Links To plugin. and set static to home. But it is displaying blank content, the header, footer and sidebar all display as they should just blank main content area. This does'nt matter if I use the domain name only as the URL or domain name/home.
If I unset the static page or set it elsewhere, home is reachable and displays as it should. The content are all in widgets on a Custom Layout Template. If I set the static page against a different page the same problem occurs for any page using Custom Layout, Default Templates seem to show OK.
So the problem seems to be the combination of Custom Layout and Static Page and as I said all pages are perfectly functional if not set to Static Front page.
Any pointers on how to fix this please!
