Ok, so your tool looks great. I haven;t actually started any indepth debugging yet for this error so this is only my initial post.
I did deploy the solution and activate the feature via the Site Settings. I was able to then activate SPThemes. I, of course, had an empty styles directory so I moved the Obsidian and Breeze themese (copie sonly) to the styles folder. When I used SPThemes via Site Settings it applied the themes as I expected. Nice.
However, when I go to the "Change My Theme" option I simply get an Unexpected Error. What is exactly supposed to happen here?
Thanks,
Stephen
