I'm trying to delete and reinstall the plugin, but no matter what I do it saves my data.
The Q&A says:
Q: I recieve an error message when trying to (re-)authorize my blog with flattr, what's wrong?
A: Please clear session/cookie/browser cache and try again please.
I've tried to close the session, remove all cookies and clear all tracks before reinstalling. I've tried with other browsers on different computers after clearing caches and deleting the folder via ftp. Still, my data in the plugin stay there.
There must be files besides the folder in the plugin directory. But where? How do I remove EVERY SINGLE trace of the plugin before reinstalling?
Please help me someone. It's driving me crazy!
