Hi,
We checked the issue on your website and found that it is not being caused by our plugin.
The AJAX request used to load the subscription form is being blocked on your site. Specifically, the following request is returning a 403 Forbidden response:
https://oldbookdepot.in/wp-admin/admin-ajax.php
Since this request is blocked, the popup cannot load for visitors. It works when you’re logged in as an administrator because the request is allowed for logged-in users.
A 403 Forbidden response is typically caused by server security rules, a firewall (such as ModSecurity), Cloudflare/WAF, or a security plugin blocking AJAX requests for non-logged-in users.
We recommend checking the following:
- Any security plugins installed on your site.
- Server firewall or ModSecurity rules.
- Cloudflare or any Web Application Firewall (WAF) settings.
- Server error logs to identify why the request is being blocked.
Once the admin-ajax.php request is allowed for guest users, the subscription form should load normally.
If your hosting provider can whitelist this AJAX request or identify what is blocking it, the issue should be resolved.
Thank you!
