ERROR 504 – GATEWAY TIMEOUT

Hey Matteo,

I plan on using your plugin pro version on the client’s site, but am facing odd behavior. It happens only when I try to save plugin settings: the wp-admin page loads endlessly, finally outputting ERROR 504 – GATEWAY TIMEOUT (This server (Web Front-End) received an invalid response from an upstream (Web Back-End) server it accessed to fulfil the request.)
Until the error outputs, refreshing the sites homepage in browser, also goes on forever.

I have tried removing your plugin and playing with just about any other plugin and settings on the same site – and all is fine + old site in the root is running flawless.

Any ideas?

Thanks in advance
