Click on other pdf in list = 404 error

I also have this issue. I narrowed it down to being a problem with permalinks.

If you set them to “plain” (https://www.siteurl.com/?p=123) archive links work fine, but as soon as you set them to anything else (like https://www.siteurl.com/%postname%/) it doesn’t work with viewer=”mini”, viewer=”presentation” or viewer=”window”. However the archive list links do work with viewer=”no”, where links post to issuu.com.

So until the plugin author fixes the issue you have 3 options:

1. Set permalinks (in wp settings) to “plain”
2. Set viewer=”no” in plugin shortcode
3. Do a quick hack of the plugin. Edit issuupress.php. Search for
   if($viewer===’no’){
   and replace no with mini or whichever viewer you wish to use.

Oh wow, thanks for the response!

I hope they fix this soon because my client really wants the “viewer” aspect of it all (it’s a monthly journal so it’s pretty important to him)!

Thanks for the temporary fixes, will try ASAP!
Thanks again!

Strange behavior. Probably related to some wordpress core update. Investigating…

OK, fix found. Using “title” as a query var seemed to cause the issue. Just pushed a fix. Should be available as a plugin update in a few minutes. Let me know if not.

btw, code is available on github. report issues there. (i don’t get emails here).

Thank you pixeline. Works perfectly now ??

Thanks a lot pixeline, everything works perfect now! You rock! Happy new years to everyone!! ??
