Sales dried up after installing optin form plugin for wordpress

Hello everyone,

i bought a wordpress plugin for generation optin form and pop up form fr my site. The site was already getting decent traffic and consistent sales before installing this plugin.

I though of capturing some of these traffic using an optin form as advised by some gurus.

However, it has been over 4 weeks since i installed the form. No only has my traffic reduced drastically, my sales completely dried up.

Let me mentioned here that in the course of installing the plugin, i had issues with it. I contacted the people behind it and they asked for my wordpress site username and password which i gave them.

I am beginning to feel suspicious about the whole thing.

Where has my traffic and sales gone to?

The plugin is a popular well recommended plugin. I decided to leave out the name for now until i confirm my fears.

Please, do you know what could have been the problem?

If you do, please kindly post your suggestions and advice.

This is actually my first successful online ventures and my heart ache as i watch my income dry up right before my eyes.

Is there anything fishy going on with the plugin?

or have i done something wrong somewhere?

Please i need your comments.

Thanks as usual.
