i have added the x-child theme, and did a few things there in the style sheet. and that is fine.
i noticed for a bit that the slider navigation had stopped using arrows, but instead some sort of shortcode?
but in any case, then the customizer stopped working entirely – even if i deactivate the child theme.
all that is now happening is the X is rotating.
steps that i have taken included ensuring 256M memory is there and available
after adding code to the wp config file.
( that was checked by viewing the backupbuddy settings)
snapshot included of console settings from firebug.
latest release of all plugins and wp and cornerstone etc.
ed
update – if i deactivate the wp editor ( one of my favorites) it started working again.
so it is resolved.
