I am running WP 3.2.1 and using Vaultpress to back up my blog. I installed a couple of security plug-ins, and now Vaultpress won't work, even if I deactivate the new plugins. Here is a list of the plugins I am running:
Better WordPress Minify 1.0.5
BulletProof Security .46.4
Login Lockdown 1.5. (This is one of the new ones).
PuSH Press 0.1.7.1 (Not sure what this is or why I'm running it--I think it was part of the default installation).
Semisecure Login Reimagined 3.2.0. (Another of the new ones)
WordPress.com Custom CSS 1.5 (again, not sure why I'm running this).
WP Super Cache 0.9.9.9
WP To Twitter 2.3.8.
Vaultpress tells me: "VaultPress is having trouble contacting your site. If the plugin is disabled please activate it before adding access information below. If you need assistance feel free to contact the VaultPress Safekeepers." On the other hand, the SFTP access seems to be set up properly: "VaultPress can directly access your site files via FTP/SFTP."
Any thoughts about what's wrong or how to fix this?
