ERROR: Failed to find flength ?

Guys,

Just add the following directives in the htaccess file.

=====

# Turn off mod_security filtering.
SecFilterEngine Off

# The below probably isn't needed,
# but better safe than sorry.
SecFilterScanPOST Off

=====

If the above method does not work, try putting the following lines into the
file

=====

SetEnvIfNoCase Content-Type \
"^multipart/form-data;" "MODSEC_NOPOSTBUFFERING=Do not buffer file uploads"



mod_gzip_on No

=====

Another options :

1. Disable the particular line for phpmotion script:
you can change the text "ERROR: Failed to find flength" file in ,cgi-bin/uu_ini_status.pl

or

make it on : my $flength_file_exists = 1;


try :)
