It is not a live site, it a localhost. I am using
WP_DEBUG for PHP/javascript code written for a child theme.
(I am changing parameters for flexslider that are
not made accessible by the parent theme)
Yes, the plugin should be updated, but the more serious
problem is that WP_Widget’s warning (not a error) breaks
the login. If I clear the cache in the browser, I can’t
log back into the admin panel without turning off WP_DEBUG
so it can set the login’s cookies. Then go back and turn
WP_DEBUG back on.
I believe it is because the warning comes during the
WP_WIDGET constructor WP_Widget() which is running at
the init hook. Normal debug messages would come at later
hooks where the header has been started and the test/set
of cookies has already been done.
I have temporarily worked around the problem by locally
modifying the custom meta widget to use parent::__construct()
but I believe the wordpress code has a problem independent
of the plugin.
