Error Encountered When Editing Content with RankMath Plugin

Hello,

I’m sorry to hear that you’re facing an error while editing your content with Rank Math after switching from Yoast. The error message ‘This block has encountered an error and cannot be previewed’ can be frustrating.

This issue might be due to conflicts between the blocks imported from Yoast and Rank Math. To resolve this, you can try converting the Table of Contents blocks from Yoast to Rank Math. Here’s how you can do it:

1. Navigate to Rank Math SEO → Status & Tools → Database Tools.
2. Look for the Yoast Block Converter option.
3. Click on Convert Blocks and confirm the action.

After converting the blocks, try editing your articles again. If the issue persists, there might be other conflicts causing the error. In that case, you can refer to our guide on diagnosing plugin conflicts here.

Thank you for bringing this concern to our attention. Let me know if you need further assistance!
