leonard, the file you’re looking for is /wp-content/plugins/wp-bitly/log/debug.txt
. Pop it open and with any luck we’ll have an error message from the http request that could help us fix the issue. If it’s short and doesn’t contain any sensitive information, please post it here. Otherwise you can send it to me directly via mark.watero.us/contact/
If you could do the same tony, make sure debugging is checked, save your settings once or twice to get a few entries in the log file, and start a new thread here with the results or send them to me at the link above if you would prefer.
