I had troubles with creating a new newsletter draft. The newsletter module did work fine for weeks. I added the 8th newsletter draft and could not save it successfully. The "Saving..." blinking button never disappeared. I deleted the draft (it showed me the 7th entry when i navigated to the new draft!). But it deleted the 7th entry instead. Now everything is blocked. When i add a new draft and save that i always get "Error". The database seems corrupt. What can I do?
