PDF++ plugin settings don't show

Bensom · August 6, 2026, 12:48pm

What I’m trying to do

The PDF++ plugin didn’t load the pdfs properly, so I had to reinstall it. (Didn’t happen the first time also) After the new installation, the plugin seemed to work just fine, but then I wanted to redo my custom annotation style, so I can use the plugin like I’m used to. After going to the settings, only the options for “editing pdf files” and “backlink highlighting” are visible and usable. Anyone got an idea whats going on? I’m fairly new to Obsidian so not too complex solutions would be appreciated:)

Things I have tried

I closed & reopened Obsidian multiple times and disabled/enabled & unistalled/installed the plugin multiple times by now.

Thats it, Thanks!

Hi Bensom,

I encountered the same issue, can you please tell me how to fix it.
(Of note, I already follow the solution in link sent by ariehen: diabled PDF++ Plugin → Turn off Obsidian → Turn on Obsidian → enable PDF++ Plugin. But this seems not to work for me).

Thanks
