Why are math equations not displaying correctly? - Talview Docs

If math equations in your assessment are showing as blank, displaying raw code, or not rendering the way you expect, this is usually caused by a syntax issue or a browser compatibility problem in Talview. In this article, you will identify the cause and resolve the display issue on both the author and candidate side.

🔎 Troubleshooting common issues

What might be wrong	How to fix it
Equation is showing raw code instead of a formatted equation	There may be a syntax error or an unsupported command. Check your equation syntax, correct any errors, and re-insert the equation. Refer to the KaTeX documentation for supported commands.
Equation block appears blank	The equation may be missing required delimiters. Delete the block and re-insert it using the slash menu.
Equation renders correctly on the author side but not for the candidate	This may be a rendering delay or a browser issue on the candidate side. Ask the candidate to refresh their browser or try a supported browser such as Chrome, Edge, or Firefox.
Nested or complex equations are broken	Complex nesting may not be supported. Try simplifying the equation or splitting it into multiple blocks.
Equation disappears after saving	Re-insert the equation using the slash menu and confirm it renders correctly in preview before saving again.
Equation renders in preview but breaks in the candidate-facing question	This is likely a browser compatibility issue. Confirm the candidate is using a supported and up-to-date browser. Mobile browsers may have limited support for equation display.

Additional Tips

Always preview your equation after inserting it and before publishing the assessment to catch any display issues early.
If the issue persists after trying the steps above, report it with the following details: the exact equation input used, a screenshot of the broken output, your browser and operating system, and the question ID.
