Hello, the site I have inherited currently runs Recaptcha 1, I believe the code to implement that is in the lines below. I don't have enough knowledge of what to change to modify this to Recaptcha 2 which the dialogue box is telling me I need to do before the end of this month, any help or suggestions are warmly welcomed.
 
I currently know next to nothing about PHP so if there is a delete this/insert this type of answer available that would be great. If it's more complicated then I need to find another way to get round this like taking recaptcha out.
 
Thanks in advance

With all due respect, you should pay someone for an hour or 2 of their time to do this for you. This site exists for developers to help others with a genuine interest in the field, which you self admittedly do not have.

 

Recaptcha implementation is in my experience relatively straightforward, but it still has to be tested. You can obviously remove the recaptcha, but expect spam commensurate with the interest that spammers might have in your community. Spambots are always at work, just randomly trying sites, and you will no doubt be spammed.

 

For a site like yours a simple customized captcha such as "Enter 'Iamhuman':" defeats every automated form filling bot in the world. They aren't built to try and understand anything non-standard. Of course if someone has targeted you they will program around that trivially.

This thread is more than a year old. Please don't revive it unless you have something important to add.
