Child Theme issues

Hi,
Yes, I have had this child theme working from the start. My original working child-theme contains: style.css with only import line, loop-page.php, footer.php, header.php

In answer to your question, the problem is that the child theme loses the drop-down template selection for pages and posts feature of the parent theme.

This issue arose when I needed to switch page template and there were no templates selection available.

Intrigued and needed a solution, I switched back to the parent theme. The templates selection re-appeared. I changed the template for the page in question. After which, I switched back to the child-theme but instead of completing the operation, WP announced the child-theme broken and reverted itself to Twenty-Twelve, removing the child-theme from possible actives.

I actually got it working again by leaving the child-them folder as is and simply changing it’s name and them name to child theme old. It unexpectedly reappeared in the themes list and I was then able to activate this “new” child theme without incident.

However, as before, no page template selection was possible.

To resolve that issue, I have now copied all page templates to the child-theme folder.

My objectives now:
1. Store only customized files in the child-theme directory while retaining page template selection.
3. Prevent future “theme broken” errors and potential theme loss.

According to reading on non child-theme friendly issues, I believe the procedure I mentioned in my first post to accomplish that. I would like comments in this regard.

Thanks!

Oh and I would like to mention, that since implementing the child theme, the pages have began loading at a snail’s pace.

I believe this slow loading issue to be related but don’t know yet how to treat it.
Regards!

Just to be sure we are talking about the same thing – when you create a new page (under Pages), you’re saying that you have no templates in the Page Attributes > Template box on the right side of the screen?

Correct.

Yes lots of widgets.

The same child-theme with the same widgets, simply renamed child-theme old works with a sidebar intact.
Once I copied over all the page templates to the child them folder, the template selection works.

I do believe something in the theme is calling those page templates inside the child theme directory instead of the parent directory.
Maybe here?
