Captcha, Mail2Form PHP problems

[MLA]

I'm at the point where I might start to cause more damage than repair...been thinking about this for too long.

I'm new to PHP so I'm at a complete loss as to what the problems are here. I'm redesigning a 'Contact' page for a website...adding a Captcha generator to it. I created the form using the Form2Mail program and inserted the Captcha Code per the instructions of the Captcha Software provider.

The errors are as follows:

To my knowledge I have all files/directories pointed in the right direction. Research I carried out yesterday claimed that the errors I stated above were due to GoDaddy (where my site is hosted) not having FreeType and GD Library enabled. I called GoDaddy and they claim both FreeType and GD Library are in fact enabled.

If that is true then this is where my lack of knowledge with PHP takes over. A live example of the webpage in question can be found at Contact Page.

Any advice or feedback would be greatly appreciated.

Config files are in the wrong locations, not sure where you have them located but you either need to change where you are calling them from or where they are located.

bluewalrus, captcha and HDWForm2Mail are in two different folders.

[bluewalrus]

So this is working now?

[MLA]

Not exactly. I've been tweaking it but it still is not 100%.

The error messages are gone but now the Captcha is not being generated. Form validation is also failing.

[bluewalrus]

You have another 404 error

not sure what that is used for though.

Your refresh captcha button calls I think that the 938 should be contained in a variable.

maybe

The lift.js is a non-issue...just a clean-up issue on my part and doesn't pertain to the captcha.

I have nooooo idea what is with the 938.

Thanks for checking in on this, bluewalrus.

I'm happy to say this has been resolved.
