I suggest taking a look at your html sanitization settings make sure html isn't allowed in markdown settings.
Next step would be to move the other 2 topics from that category and check if you still see broken markup.
I have successfully been able to bind my domain to my nodebb installation , but upon trying to login to my nodebb install via the domain name , I get errors like :
Failed login attempt, please try again. Forbidden
invalid csrf token
We were unable to log you in, likely due to an expired session. Please try again
How do I get rid of these errors and get login to work smoothly?
nodebb version : 1.10.0
nodebb-theme-vanilla version: 10.0.16
Check the url value in config.json and make sure it exactly matches the url at which you visit your site (including protocol).
Yes, it is same. But error is still there.
