Multiple Instances Crash

Using multiple instances of the plug in in same sidebar element gives error.-

Using multiple instances of the plugin in different sidebars works, but there is a problem with the catched data if you have 2 diferent accounts to show with the widget.-

My solution until an update was to remove the catched data just replacing the 60 seccons to 0.-

if ( $tumblrcache[‘lastcheck’] < ( mktime() – 0 ) ) {}
