I’ve completed the server move and the DNS changes, so hopefully everything will now work. There was a problem with the email program (cgiemail) during the transfer, but it seems as though I resolved the problem by using a different script (FormMail). Please feel free to send me an email or leave a comment in this post if there are any problems.
As an added bonus, I’ve attached some pictures of sparks generated with my high voltage power supply, which I was able to fix. It appears as though the old MOSFET had blown, so I was able to recreate the circuit with no issues. Continue to the post for a few more pictures.
