Hi, I got the last character stripped when using a suffix.
So, if we have a slug something and a suffix html, we end up with an url like somethin.html.
I'm using /%postname%.html globally.
I hope this can be solved changing line 124 and 125 of file remove-slug-custom-post-type.php:
if (!empty($suffix)) $permalink = substr($permalink, 0, -1) . ".{$suffix}";
To:
if( !empty($suffix) )
if( substr($permalink, -1) == '/' )
$permalink = substr($permalink, 0, -1) .'.'. $suffix;
else $permalink = $permalink .'.'. $suffix;
Best. :)
