I Was using native onepage checkout of magento 1.9 till now. Came across IWD OPC and thought of integrating it. Features, for a free extension, are great.

After installation, everything worked well with admin side. But the on the cart page, frontend, I **could not see the "proceed to checkout" button.**

I checked **/template/checkout/cart.phtml** and found nothing.

tried to google the issue but couldn't find exact issue. Is there anyone whoo has come across such issue? If yes, did you resolve it? If yes, what did you do to make it work?

[UPDATE][SOLVED]
----------------

For this particular issue, i tried a lot of things but finally one thing solved the issue.

Steps:

1. after adding an item to Cart, I tried the direct one page URL in the browser. i.e., <https://domain.com/onepage>
2. It showed issue while reading the `GeoIP.dat`  file.
3. went to console, did

 `sudo chown -R www-data:www-data lib/MaxMind`   

 `sudo chmod -R 777 lib/MaxMind` 

4. refreshed the page and IT WORKED.
