Error -- Could not open /home/ec-securehost/cgi-bin/jman/uploads/lock to write file lock

A lock is a file which is written before modifying the data and removed afterwards to prevent corruption by two simultanious processes. The directory, /home/ec-securehost/cgi-bin/jman/uploads/ has been defined on lines 6and 7 of the marcart_well.pl script.
The marcart_well.pl script must have read/write permissions to that directory in order to place the file lock.

You can disable the file lock on the "customize pages" screen.
