WPBakery CSS Generator not working – Cloudflare blocks server requests
-
Hello,
We are using Woodmart theme v8.4.1 with WPBakery on our store tochilkazhuk.ru.
We tried to use the WPBakery CSS Generator (Tools → WPBakery CSS generator) to reduce the size of js_composer.min.css (456 KB).
The problem: when we click “Generate file”, the generator makes a request to woodmart.xtemos.com from our server via PHP curl. But woodmart.xtemos.com is protected by Cloudflare, which blocks server-side curl requests with a challenge page (“Just a moment…”).
As a result, the generated CSS file contains Cloudflare HTML challenge page instead of actual CSS. The file is saved to /wp-content/uploads/ but is unusable.
Could you please help us resolve this? Specifically:
1. Is there a way to whitelist our server IP on woodmart.xtemos.com?
2. Or is there an alternative way to generate the CSS file locally without calling your server?
Thank you!
Hello,
We have added an exclusion for this. Please try to generate it now and let us know if it helps.
Kind Regards
Hi Artem,
Thank you for adding the exclusion. Unfortunately it’s still not working — the generated file still contains Cloudflare challenge HTML instead of CSS.
Our server IP: 85.239.48.185
The latest attempt was just now (timestamp 1772703168). The file at /wp-content/uploads/2026/03/js_composer-1772703168.css starts with <!DOCTYPE html> and contains Cloudflare “Just a moment…” page.
Could you double-check the exclusion? Perhaps the IP wasn’t whitelisted correctly, or Cloudflare needs time to propagate the rule.
Thank you!
Hello,
Please send us your admin access so we can troubleshoot why it doesn’t work on your website.
Kind Regards
Hi Artem,
Please note:
– We use xCloud hosting (nginx + PHP 8.3 + Redis)
– Server IP: 85.239.48.185
– We have FlyingPress caching plugin active — please purge cache after any changes (FlyingPress → Dashboard → Purge & Preload Cache)
⚠️ Important: This is a live production store with real orders. Please do NOT deactivate or delete any plugins during troubleshooting. If you need to test something, please let us know first.
The js_composer.min.css (46 KB, 99% unused on most pages) is the biggest remaining CSS performance issue on our site. The generated file at /wp-content/uploads/ was previously returning a Cloudflare “Just a moment…” challenge HTML instead of CSS — as reported in our earlier message. We’d really appreciate your help resolving this.
Thank you!
