[SOLVED] do_upload and the dreaded "The upload path does not appear to be valid"

didja try hard coding the path?

Code:

if ( !write_file('/path/to/mamp/public_html/CI_stuff/images/file34.txt', 'test test test test'))

as for the error logs... did you turn error logging off? never turn it on? not looking at the right log file built into CI?
