Syntax error when submitting a review

I keep running into a syntax error from time to time, and it’s really frustrating. I just spent about 30 minutes writing a detailed review for a solid source, but when I tried to submit it, an error popped up and the entire review was lost.

Is there any way to prevent this from happening again? Or is there something specific the site might be detecting that I should avoid when writing a review?

Thanks in advance.
