[Plugin: Post Thumb Revisited] AutoUpdate version 2.2.1.b is not working

While trying to do an auto update of the plugin
Wordpress says the update worked
and if i look at the file it says Version: 2.2.1.b

but when I go back to the Plugin page
It is still showing that I should update

I am not sure where you put in your plugin the current version
so Auto Update knows what version is available
but maybe double check

ALSO I am getting a lot of header errors when using other parts of the dashboard and the error points to this plugin shooting out headers
so maybe there is a bad character or space someplace it shouldn’t be.

Just as a note it would be good
to not show the Default Thumbnail Image
if there is no image in the post

thanks for the plugin
