How To Remove All Prefs from Prior Version?

Hi,

I want to completely reinstall my Responsive DP Theme 4.5 from scratch. I went under Themes under the Theme Installation area in my WP Admin and did the ftp delete of this version.

Then I reinstalled it but it retained all my customizations. I did this several times to no avail. Deleted cookies. Quit browser, logged back in. Re-uploaded the fresh zipped 4.5 theme and it still keeps all my settings, even my custom css.

I deleted 4.5 and uploaded 4.7 hoping this would clear it all out and it now has my customizations.

I even refreshed my folders via ftp after I deleted the theme to make sure my server updated itself but the “stuff” is still there. 🙁

There is obviously some cached folder on the server in my WP installation that I need to remove manually.

The System Cleanup Modules in the Toolbox are not comprehensive enough – I do not see a wipe it all clean including design and colors option to bring the theme back to its original form.

Can someone please point me in the right direction to remove the stored/cached data?

Thank you! 🙂
