Thank you for creating such a useful plugin! I use it extensively at http://www.fashionandstyledirectory.co.uk/ to display different banners on different URLs.
It has worked great to date, and just today I set up a new homepage banner. This evening, however, I'm finding that when I click through to edit the dynamic settings for a previously setup widget, the green tick next to 'URL' is gone and my exceptions listed in the box under the 'Show widget at this URL?' heading are all missing. The settings are still working, though - all the banners are displayed on the right pages as before - I just can't see the details to edit them any more.
Similarly, if I create a brand new text widget and give it dynamic settings, these are successfully applied to the site but have no tick and are not visible for me to edit once I save them. In the main interface, however, WordPress knows that I have 'Options set for URL and Directory' - I just can't see those options once I click through the 'Dynamic' link.
I haven't installed any new plugins since this afternoon, and I've tried uninstalling and reinstalling Dynamic Widgets without it making any difference. I've also deactivated all other plugins, with no difference.
I'm a bit stumped! Any suggestions? Basically, I can currently create new dynamic widgets, but can't edit any that already exist without re-entering all the options from scratch.
