Persona/Light Theme Maker Stopped Working Topic is solved

[Zirconia Wolf]

So I'm a recent Pale Moon convert & have been having fun customizing my browser these last couple days. Along those lines, one of the first add-ons I installed was the Persona/Light Theme Maker, which has been working fine until about an hour ago. Now whenever I try to use it, I see the "edit" page like usual, but none of the edit, select, or create options work. I've tried uninstalling/re-installing the add-on, but the problem remains: None of the features work anymore.
(See mini-screenshot: The UI transparency controls are gone, there is no list of themes to select, & clicking on the "+" button does nothing.)

Is there a way to fix this without a wholesale Pale Moon reset? Honestly have no idea what triggered this: it was working fine until it suddenly wasn't.

OS is Windows 7 Home Premium, SP 1, 64-bit
Browser is most recent Pale Moon
Other info available on request (wasn't sure what else to include)

Thanks for any advice/info.

"Persona/Light Theme Maker" uses its preferences, in "about:config", to write its option page. One or more of these preferences may be missing or corrupt, causing the options page to display improperly.

To fix, first try resetting "Persona/Light Theme Maker" preferences in about:config. Open about:config. Then enter ".{f0220c", or until the "extensions.{f0220cf6-8b2c-4103-9e8c-5b7215db3158}." preferences appear. Reset the four preferences shown below, to their default values.

If reset of these four preferences doesn't work, uninstall "Persona/Light Theme Maker". Then, make sure there are no remaining "extensions.{f0220cf6-8b2c-4103-9e8c-5b7215db3158}." preferences in about:config. If so, reset these preferences (and then restart Pale Moon to delete them). Then, reinstall "Persona/Light Theme Maker".

To lessen chances of future corruption, promptly close the "Persona/Light Theme Maker" options page, i.e. don't leave open, after making changes.

Thanks for the tip; I'll go check my config settings right away.

After thinking about the problem more, I realized that the trouble started right after I had deleted a "test" theme I made just to see how it worked. It's almost like instead of just deleting the "test" theme, it or I somehow deleted all the pre-installed theme options. (Not claiming that's what actually happened, just thinking back on what I was doing before everything went screwy.)

Anyway, thanks again for the explanation & especially the picture. Very helpful!

********** UPDATE **********

Took a look at my config settings, found the 4 Theme Maker lines & they all looked okay, except on the 3rd line where I only had a [] entry.

So I changed it to [{"name":"Grey",}] closed/restarted Pale Moon, fired up the Light Theme creator & it worked perfectly!

Thanks for the excellent instructions! (Think I'll go snag a copy of that backup-settings addon I saw listed, just for safety's sake.)

Thanks again!
