i ran into a similar issue so you could try these steps:

pgrep for any running deluge processes and kill them.
remove deluge lock file ~/.config/deluge/ipc/deluge-gtk.lock
start deluge-gtk from console

you need the latest version 0.14.9 for 1.2.1 plus have you installed python-libtorrent

It just so happens someone with a similar issue posted a question and i am guessing you meant to write you got the error 'import error simplejson' NOT simplejonh!

http://forum.deluge-torrent.org/viewtop ... =7&t=30095

you need libtorrent-rasterbar

To remove Deluge you should do apt-get purge deluge and manually delete any other remaining files.

To install specific versions with apt-get follow the details here

ImportError: No module named simplejson

This suggests python-simplejson is not installed

Use the latest version 1.2.1 from PPA instead

I don't have the answer but I would say you need provide these details at a minimum so that others can help...

Deluge version
Packaged or built from source
Operating system
Web browser

Also make sure you have you checked the FAQ

typing 'config' in deluge-console gives a list of all the options for use with --set >>> config add_paused: False allow_remote: True auto_managed: True autoadd_enable: False autoadd_location: /home/user cache_expiry: 60 cache_size: 512 compact_allocation: False copy_torrent_file: False daemon_port: ...

Great plugin Tomsoul, you should create a wiki page for the Plugins list

im sure you need to use full path to script/app with cron

edit: i see you did find that solution
