Website Troubleshooting and Fixes

We are experiencing several issues on our WordPress-based website, and we need an experienced freelancer to help resolve them. Below are the key tasks that need attention:

Tasks:
1. Revolut Payment Gateway Issue:
• After integrating Revolut as a payment gateway, the checkout process freezes or takes a long time when customers click “Place Order.” We need this to be fixed so the payment gateway functions smoothly.
2. Contact Form Email Issue:
• The contact form on the Contact page is not sending emails to our Gmail account as it used to. This issue appeared after adding Cloudflare. We need the email functionality to work as expected again.
3. Subscription Form Issue:
• The subscription email form at the bottom of the homepage redirects to a blank page with no content when clicked. This needs to be fixed to allow successful subscription sign-ups.
4. wp-config.php Issue:
• We are unable to change or download the wp-config.php file. This issue needs resolution to manage the site configuration properly.

Requirements:
• Experience working with WordPress and resolving issues related to payment gateways, contact forms, and server files.
• Familiarity with Cloudflare and potential conflicts it may cause.
• Knowledge of wp-config.php file management and troubleshooting.
