• 1 Did you use &nbsp or   ? And what's the exact wp_kses() code you used? – Sally CJ Commented May 25, 2019 at 11:46
• @SallyCJ not sure the difference but i used &nbsp for adding a white space ..then passed it through wp_kses() – user145078 Commented May 25, 2019 at 11:50
• 1   is the correct one - the ; is required. Otherwise, that's an invalid HTML entity and &nbsp would result in &nbsp. – Sally CJ Commented May 25, 2019 at 11:52
• 1 @SallyCJ thank you! worked. – user145078 Commented May 25, 2019 at 11:56

not sure the difference but I used &nbsp for adding a white space ..then passed it through wp_kses()

The correct HTML entity for a non-breaking space is   — note the ; which is required and without it (i.e. &nbsp), the entity is not valid and when used with wp_kses(), you'd get &nbsp instead of a non-breaking space.

strangely it was working fine before I used wp_kses()

I'm pretty sure it's because the browser is smart enough and auto-corrected it to  . :-)

So, always use valid HTML entities and also tags (e.g. close a <div> with a </div>), regardless you use wp_kses() or not. Don't rely on "intelligent guess" or auto correction by the browser.
