An update on my WordPress problem with the single post pages just producing HTML gobbledegook.
It is a permalinks problem. My first attempt at testing that proposition a few days ago failed. I changed the permalinks to the default and the problem was not resolved.
Reflecting on the differences between my blog with the same theme and mostly the same plug-ins led me to the solution. Set the permalinks to /%year%/%monthnum%/%postname%/ just like the blog. Hey presto they work.
Then I read the manual: http://codex.wordpress.org/Using_Permalinks which offers a caution about just using /%postname%/ but does not say it does not work just that it may cause performance problems.
So now my News, Events, FAQ and other future post categories will be preceded by the year and date of publication. An unecessary distraction in my view. However I may publish posts with the same name sometime and this will stop that being a problem.
Anyone know how to stop the Before and After post links above the post title pointing to posts in different categories? i.e. if you are looking at a News post, I don't want you to see a link to a FAQ.
