Whenever I start AutoWIkiBrowser, it generates an error saying that "StartIndex cannot be negative". This might affect others too, so please consider changing "StartIndex" to a positive or zero value ASAP.
You're very much misinterpreting the error... It doesn't work like that, we're not choosing the StartIndex manually
I'm suspecting this is also T233070: AWB log in fails when reading temporarily-empty InitialiseSettings.php.txt.. What version of AWB are you using?
