After years of using it, the Jetpack plugin we had suddenly disappeared from our WordPress. Extremely bizarre. So we’ve reinstalled it (using FTP, as wouldn’t install otherwise as folder already existed).
Whenever we try to activate it, it says:
“Access denied for user ”@’localhost’ (using password: NO) on line: 1471″
Because of the “access denied” I thought you may have been using a paid plan
But if you are using only the core features
Is Jetpack free?
Yes! Jetpack’s core features are and always will be free.
These include: site stats, a high-speed CDN for images, related posts, downtime monitoring, brute force attack protection, automated sharing to social networks, sidebar customization, and many more.
Then I’m fairly certain the “access denied” and “user localhost password no” are a database connection failure.
If you look at line 1471 you should be able to see in what context the error is from.
Can you think of anything you did between the last time you knew it was working and the first time you noticed it wasn’t working?
