I’m talking to a friend right now with the same issue..
After the 4.1 update the tool bar vanished.. disabling all plugins and switching to default theme changed nothing. All updates are current
The site has a single administrator, and she is still listed as the Administrator, so that’s not the issue
Similar Problem here, all recent
I’ve been using the plugin for a year, At most once or twice a month a stray bot would get through.
For the last week or two it’s been daily at the rate of 3 or 4 a day.
Then last night I got hit, woke up to 22 of them and 6 more in the last couple hours..
