Update isn't working

Any idea? This is how the screen looked like when I tried to update:

Unpacking the update…

Installing the latest version…

Removing the old version of the plugin…

Plugin updated successfully.

Plugin failed to reactivate due to a fatal error.

Parse error: syntax error, unexpected T_DNUMBER in /home/spydivo5/public_html/wp-content/plugins/simple-post-template/simple-post-template.php on line 35
