I had installed the WP Widget Cache and then all of the sudden ALL of my widgets were gone with this error message in each place:
Warning: Illegal offset type in /home/marta28/ohmymarta.com/wp-content/plugins/wp-widget-cache/widget-cache.php on line 504
I deleted the wp widget cache plugin. Deactivated all of my plugin and removed all of my widgets. And then added the plugins and widgets back except for the WP Widget Cache.
Still getting the same error message.
I'm extremely NEW so pretty simple directions please!!!!
