How to get rid of PHP Notices in Toolbar Extras v1.3.0

In Toolbar Extras version 1.3.0 there was a little bug which could led to the display of unwanted PHP notices in some installs.

To get rid of those notices just save the plugin’s settings again: WordPress Settings > Toolbar Extras
There save the “General” tab once, plus the “Smart Tweaks” once.

Then all is back to normal.

The bug was fixed in version 1.3.1.
