Body tag closed twice

That’s weird … I’d like to have a look at the full HTML source, can you post your site’s URL here (or put it in a mail, futtta at gmail dot com)?

I too get this error (when viewed in ‘view page source’) :

/* */</script><script type=”text/javascript” defer src=”https://vrpdev.nammavidyaranyapura.org/wp-content/cache/autoptimize/autoptimize_f30351c32e48108773d9e89f902bede8.js”></script></body>&lt;!–noptimize–><!– Autoptimize found a problem with the HTML in your Theme, check if the title or body-tags are missing –><!–/noptimize–>

It is on a DEV site.

In general that error is printed if your theme is missing <title> or </body>-tags, which autoptimize needs to be able to insert the links to optimized js (or css). if those are not found, AO just adds the links at the bottom of the HTML and prints out that warning.
