Hello,
I’m sorry to hear about the critical error you encountered on your website. If your hosting support mentioned that the issue was caused by Rank Math’s free SEO plugin, it might be due to a conflict with another plugin or theme on your website.
To resolve this problem, we recommend performing a quick conflict check to confirm if it’s a bug or just a theme/plugin conflict. You can use the Health Check plugin to do this without affecting your website visitors. Here are the steps to follow:
- Installing the Health Check Plugin:
- Log into your WordPress Administrator account and navigate to the dashboard.
- Go to Plugins in the WordPress menu and then click on Add New.
- Search for ‘Health Check’ in the search bar and install the Health Check & Troubleshooting plugin.
- Activate the Health Check plugin.
- Find the Site Health option by hovering over Tools in the WordPress Menu and clicking on it.
Performing a conflict check using the Health Check plugin will help identify if there is a conflict causing the critical error on your website. Once you have identified the conflicting plugin or theme, you can take appropriate action to resolve the issue.
If you need further assistance, feel free to reply to this ticket, and a human agent from our support team will assist you promptly.
Thank you for bringing this concern to our attention.

Confirming a Theme/Plugin Conflict With Rank Math
Ok, I tested all plugins with a health check, and it seems that the only time when the problem is fixed is when I disable the rank math plugin. I can not see a conflict with the other plugins.
