For some reason, in the Dashboard - The right column of the widget area has vanished.
I can no longer see the areas of my theme where I can add widgets. This has been working for many years but I'm unsure when it stopped working - I only recently tried to update the sidebar and found the issue.
I have already tried the following:
deactivating and re-activating all plugins
re-installing latest version of WordPress
re-installing the theme
manually reinstalling the wp-admin and wp-includes folders
None of these have made any difference.
I CAN manually add items to the widget areas by enabling "accessibility mode", but I can't delete or edit any of the widgets as they don't appear anywhere. This offers no solution to the problem really.
Can anyone shed some light on this issue? Anyone help!?
