Gibberish values when using the php shortcode.

After updating to the latest version when i checked my site the whole site was filled with Gibberish values,

this was in my local setup,

I went and looked in the codes and i found that in this file
“insert-php-code-snippet/shortcode-handler.php” line number 16,17
“if(strlen($tmp)>0)
ob_clean();”

these lines were responsible for the issue, so i went and changed the ob_clean to ob_end_clean();

“if(strlen($tmp)>0)
ob_end_clean();”
And this fixed the issue, for now.
Not sure if this was right here, will there be a problem if the buffer is cleaned and turned off before starting it again.
