 * Hi RankMath team,
 * I’m having trouble with the SEO analyzer. Every time I try to check it, I get
   an “API Error: HTTP 400 error”. Can you help me resolve this issue?
 * I have already tried all the documentation available on the internet or in the
   knowledge base of yours but issue not solved.
