Hi. Do you use the plugin WP external links? For me, I had to un-click apply to all pages.
This happened after I uninstalled mojomarketplace from http://www.sskimages.com (a domain i don’t use anymore). Uninstalling mojo marketplace removed main files from http://www.talesfromafork.com (domain I use now), which then my hosting company had to use a daily backup to restore my site. Then my toolbar stopped working properly.
