Last two years I am using this plugin and still its working good but now sharing to Facebook not working in my all sites. Whenever I connect it to Facebook that time it works after that is doesn't posting to Facebook.
This is so helpful and very useful plugin. Not complicated. To be honest I was sure before installation. In description it was looks little bit complicated. Very nice solution and fast support! Thanks!
Super nice and smooth plugin. Really like some particular functionality , for example backup and security tools.
The images were all resized to be very small (after enabling lazy images). The performance was not very good as a consequence. The backup Vaultpress never worked once in two years despite paid subscription. Once the Vaultpress FTP / SFTP access were activated, the server went down a few minutes later due to total overload, so I had no website access for about half an hour until I managed to pull the plug there. I tried the website with, and without Jetpack and it just so appears that without it is quite a bit better. Unsubscribing was interesting. The people had put an interface without button for canceling the subscription on my portal, so I went to Paypal to stop payments there and wrote them a message. The help desk was very friendly in writing me what I already knew (some part of their software could not access my site) but I had to find the relevant htaccess edits elsewhere, as the Jetpack / Vaultpress people appeared unable to provide any practical help. Even that was not sufficient to force the stuff into submission so I guess this is for other websites maybe.
