My site has a very large database of 100MB, most of this is in a table called cache_form.
I've tried clearing the cache. When I try and run the cron I just get a white screen.
My site is in maintenance mode, is it safe to delete the contents of this table in PhpMyAdmin? There are clearly some other issues that I need to look into but is it safe to do this as a short term measure to get the site back on its feet? I've had to put it in maintenance mode as aspects of content creation have stopped working properly.
