first make sure you have the correct answer (which is to split up the selectors, do not combine them).
Then turn off all your browser extensions and retry this step.
(it is known that browser extensions and add-ons will interfere with this step so they must all be disabled for this step)
Same issue. Turned off browser extensions but still does not pass. Why would an extension affect this specific problem and not other syntax checks? The answer is correct, the FCC method of checking the answer must be flawed: error says do not change H1. I have not changed the H1. This is simple separation of multiple type selectors via a comma. The preview shows the code is working. Even if this was caused by a browser extension the error message is still incorrect. Chrome Version 107.0.5304.87.
