An API key must start with‘ test_’ or ‘live_’ and must be at least 30 characters long. I had the problem first with the old version of the plugin. Then I updated to 2.0.1 and this temporarily solved the problem, I could access the plugin settings. I (rather stupidly) typed something in the API key field as a placeholder for my customer to paste their API key, but now I can’t get rid of it. Is there a database field that can be emptied? I have tried re-uploading the plugin via FTP but no success. Any help is greatly appreciated. Thanks!
