[BUG] Tampermonkey Classic (Safari) unable to access Dashboard

[irandamay]

Actual Behavior

I wanted to export all my personal scripts to have a backup, but I realized I cannot access the Dashboard anymore. It just brings up a blank white page and there are script errors in the console for topee-extension.js

Expected Behavior

Expected the dashboard with all my scripts to show up so I could edit/export/etc.

Steps to reproduce the issue

1. Click on Tampermonkey icon in Safari
2. Click Dashboard
3. New tab opens with url of https://ui.tampermonkey.net/options.html#url=[...] but it is a blank white page with no dashboard.

Screenshots or Screencasts

Environment (please complete the following information)

• Browser and Version: Safari 26.4
• Tampermonkey version: Tampermonkey Classic 5.3.6218
• Operating System and Version: macOS 26.4

Additional context

The dashboard had been working up until a few days ago. I thought a third-party script I was using was broken and have been checking for updates to it every few days for a while, so I know that it was working within at least the last week. It may have stopped working when I updated to Safari/macOS 26.4, I do not know if I checked the dashboard after I ran that update last week.

Having the same issue! Can't edit my userscript out of this at all!
Is there any workaround for this?

Downgrading Safari to 26.3 can workaround this issue. Hope that works.

Is there any other workaround besides downgrading Safari?

I got around this issue by using Safari Technology Preview. It let me get into the Dashboard to download a backup of my extensions. I then went to the App Store and bought and installed the new Tampermonkey (paid upgrade). Then I imported my script file into the new Tampermonkey and removed Tampermonkey Classic. Not ideal, but at least I'm up and running again.
