The contact form on my blog was working perfectly and I am receiving all messages sent through it. Then from one of the articles, I have learned that someone has been trying to contact me using the form. I checked it and the captcha is missing. I reactivated it then tried it myself. Unfortunately, after several messages, I am still not getting any emails from the contact form 7.
I investigated and I found out that there are several WordPress upgrades already including the contact form 7. I tinkered with the settings but still not able to find what is wrong with it. I tried seaching the net for the problem and solution but I was not able to find any suitable solution. I only found problems and not even the particular problem that I am having.
I tried installing the Fast and Secure Contact form plugin which works but I am not satisified with it. Probably, I will be creating my own contact form customized to my requirement. While that is still not happening, I will content myself with FS Contact Form.
