The line 206 warning only seems to come up if you manually insert the function to display and do not select “Manual” in the plugin settings. But then the warning points to line 415. And it’s not entirely consistent.
Just pushed up the latest version (1.4.5), you should see it appear in your WordPress upgrade panels shortly.
It turns out if you deselect all of the Custom Post Type display options, it leaves us with an empty field. Another contributor added this function and I didn’t catch the issue. If this was left blank, in_array starts to complain.
Its been fixed, be sure to follow up if you see any other issues.
Thanks for all feedback and for using WPSocialite!
