Lost customization on changing WP directory

[LVDeF]

Hello !
First of all, sorry for my bad english. I'm french, and I do my best...
And thank you so much for such a nice pluging !!!

When replacing a website with a WordPress solution, I prepare the new version in an under-directory.
When it's ok, I replace the old one in the main/online directory.
I change parameters following WordPress notice for doing that.
But I lose custom parameters of Admin Color Schemer.
Il looked in the database / usermeta table trying to find a bad url that should be changed, but nothing that seem to be wrong.
How could I fix that ?
Thank you in advance for any information !
Regards,

The URI to the stylesheet is stored as a part of the option, you likely need to find that and change it as well.
