WooCommerce Categories Pages Not Working – Permanent Fix Needed

I have been facing an issue over the last two days where specific WooCommerce category pages intermittently show a “404 Page Not Found” error, particularly during the evening.

Affected pages include:

https://standardcoldpressedoil.com/spices
https://standardcoldpressedoil.com/himalayan-salt
https://standardcoldpressedoil.com/honey

Current Configuration

I am using the “Strip Base” feature in the Rank Math SEO plugin, which removes the /product-category and /products prefixes from WooCommerce category and product URLs.

Observed Behavior

The “404 Page Not Found” issue occurs intermittently, causing the above category pages to break.
To temporarily resolve this, I have to deactivate and then reactivate the Rank Math plugin each time the issue arises. So that these categories pages started working.

Questions and Concerns:

1. Why does this issue keep happening?
2. Is this related to WooCommerce, Rank Math, or server settings?
3. How can this issue be permanently resolved so that I don’t need to deactivate/reactivate the plugin repeatedly?

Expected Resolution

I need a permanent fix for this issue so that the affected category pages work consistently, without requiring manual intervention. Kindly investigate the root cause and provide a solution as soon as possible.

Looking forward to your assistance.
