Theme Defaults to “Default” Automatically

Hello,

I’ve been using the Cutline 2.1 theme since upgrading to 2.3. Unfortunately, after about 24 hours or so after selecting the Cutline theme, my website defaults automatically to the “Default” theme. I have not been able to make this stop, even after upgrading again to 2.5.

Does anyone know why this is happening? Could it be a fault in “default” or in “cutline” or in both? By the way, I use Netfirms as my host (a known culprit of screwing up wordpress!) and use FlickrRSS plugin instead of cutline’s random image rotator.

If you’ve got any ideas, please let me know. My website is http://www.missadventures.com.

Thanks,
Melanie
