• My site keeps generating error 503 screens. The error log says Failed to read FastCGI header which my host says is caused by fault php and recommends isolatig the errant plugin. MailPoet active gives me a CPU usage of between 65 to 75%, inactive my cpu is 40%. Disabling any of the other plugins makes no significant change

  • Hi Patbell,

    I hadn’t connected the dots – I was getting 503 screens before I got the 500 screen I complained about this morning.

    I have disabled MailPoet for the time being as I suspect that it is causing the problems and needs looking at.
