Before:

When I set a content in YCWP QR Me Configuration, for example, Content:Post Permalink, the resulting QR is from “chl=(blank)”…

You set a permalink of post by filtering, but in my case(or every case) that filtering happened after generating QR code. So when getting url, $this->_the_permalink is blank…

I added small code using global $post variable temporarily.
You(Original developer) may adapt it more elaboratively.

I modified

$qr->set_content( ‘simple’, $instance[‘content’] );

to

$qr->set_content( $instance[‘content’] );

This sidebar widget works well afterwards.

Thanks for making this very good plugin.

I run a plugin that gives me 404 error codes. This one continues to show up. It seems there is a missing / in plugins and ycwp-qr-me.

wp-content/pluginsycwp-qr-me/js/jquery-easing1.3.js?ver=1.3

I am not sure where the error is coming from.
