New account register error

Hello,

I am facing this error in my opencart store version 2.1.0.2.
Whenever anyone tries to register at my store, they get an error "Server Error 500" after submitting the details.
My store url is www.stayhome.co.in .
I have checked htacess file as well seems like it is correct. Also uploaded all original files again. Still the problem persist.
May be it is something related with customer.php file.
Please Please Please help me.
Thanks in advance

First of all, you need to enable displaying the error instead of just giving useless 500 error.

Hello tabook,

Thanks for your reply. I have enable displaying the error. Still its showing the same.

what was the last thing you modify?

Do you have a backup?

I have not modified anything. Even I have replaced all opencart file as well.

There will be more detailed log entries in your server's error_log for your 500 Error, ask your webhost for them. Without them, we won't be able to help you.

did you modify the htaccess lately?

The problem is resolved.
I was checking the error log of opencart instead of the server's error log, sometimes my mind doesn't work properly, but thanks to @JNeuhoff for suggesting me to check server log. And it turns out a useless extension was causing this problem. I have uninstalled it and ta-da it's working fine now.

Thank you all for helping me out.
God bless all of you.
