How do I solve the "can't parse message text" issue?

For markdown-style formatting, make sure that the message text does not contain extra *, _ (often occurs in links and hashtags) and `. In case you find some, paste a backslash \ before them to fix. So the bot will not parse these symbols, and the error message should gone.

If you have HTML-style formatting enabled, check the message text for <, > and &. Replace them with the corresponding HTML entities (< with &lt;, > with &gt; and & with &amp;).
