Just checked my site and the home page changed settings again in the ‘Readings’ menu and I had my posts as the Home page. I haven’t touched WP since I changed it back two days ago.
It seems to be a problem with your theme which is either wrongly edited or outdated. Revert to Twenty Eleven theme and see if the problem persists.
It’s not outdated, I have the latest version. I’m hesitant to change to Twenty Eleven as I’ve not used it before and imagine I would have to spend hours reviewing and editing pages. I’m on a two week trip with no time to learn a new theme much less do the work to make it look right.
I am admittedly not experienced at this. Someone else set up the site and I’m doing it now and learning as I go. As an example, when I ‘Live Preview’ my site in Twenty Eleven, the menu picks up titles that I don’t want there. I’d have to figure out how to eliminate them.
I’ll just have to keep monitoring it and changing it back every day till I get home and have time to work it out.
I appreciate you taking the time to help and offer suggestions. ….Michael
