I'm currently having a few dramas with my site. Seems that every so often it decides to ignore my chosen theme (k2) and reverts to the default (kubrick) theme.
To fix I'm having to check my site periodically to ensure that my selected theme remains in place and when it's not, log back into the admin panel and re-activate my chosen theme.
I've re-installed WP2.0.1, deleted, re-installed and deleted my custom theme, deleted and re-installed the K2 theme, deleted my tables and re-installed from backup. Only themes currently installed are the two defaults + K2, active plugins are restricted to Akismet, Related Posts, Markdown, Dunstans Time Since, Extended Live Archives. I'm frankly not sure what else I can do.
Any help is diagnosing and fixing this issue would be much appreciated.
