GSconfig UI [v0.3]

[Tyblitz]

I did not copy the field, I just generated salt and hit Save

Ok weird. I cannot reproduce. 
- Which version of GS Custom Settings are you using? 0.4 or 0.5? 
- Do you remember which of the salt settings (login vs. cookie/uploads) you changed?
- With the fix I posted above, does the problem still arise? (if you retry, try with a word like 'admintest' & not a salt, so you'll easily be able to navigate back to your admin panel)
