I have updated. Errors are gone, but the plug-in tag functions are not showing up in tag box on the edit or manage screens.
I am having a near identical problem
my error is:
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /****/****/public_html/trooper/wp-content/plugins/wp-extags.php on line 77
I have just downloaded and installed the plugin at 4:50PM CST.
