Cannot save theme settings

Hi everyone,

I have rather a big problem with one of my sites using an Omega subtheme.

Somewhere along the line, all settings have been changed in the theme so EVERY weight setting is -50, and EVERY column width setting is 1, and the grid settings are normal weight -10, narrow weight -10.

I did a core update, and some module updates, but this only affects this one site, I have 2 others also using the same core and same modules in a multi site setup.

The live site in question works ok now. As it stands, the old settings are still in use but if I were to save the theme settings, it would go terribly wrong!

I made a local copy, opened up, went to theme settings and saved and the above changes were applied (column width = 1 etc...) thus breaking the layout completely.

I have changed to a different omega subtheme, a generic one I use as a starting point, and in the settings, the same! -50, -10, column width = 1. I can only conclude that these numbers are in the database somewhere.

If I change the weight of, for example, the narrow or normal grid (to 0 and 1 respectively) and press save, I get no error, just that the settings have been updated. However, they are not, they are back to -10 and -10 respectively.

So I can't even change to a different omega subtheme. All other themes (i.e. bartik) work ok and settings are saved successfully.

Maybe if I could remove any reference to omega theme from the database, I may be able to start fresh. Building the theme again wouldn't be a problem as I have all the css and know what the sites layout looks like.

As I said though, I can't use another omega subtheme even though it's fine on all the other sites. I can only think database error somewhere.

Anyone have any idea what is going on here?

Thanks.

Sam.
