I meant to link that topic and not loop-link this current topic:

> Hi Philipp, I encounter the same issue with Panel 0.11.3, I had to downgrade to 0.11.1 for my project to work. The problem appears starting 0.11.2. The bug is still the same : the URL of the CSS are relative, not absolute. Thus, if I serve bokeh documents (with port 5006) via Flask (port 8080), Panel CSS are loading with port 8080 instead of 5006. # from flask app, when reaching 127.0.0.1:8080 script = server\_document('http://127.0.0.1:5006/bokeh\_page') return render\_template("embed.html", s…

so we have a flask server serving an application to several LANs, and one of them has no internet access. This is problematic only since tabulator was added, it was working flawlessly before as only bokeh models were loaded.

These three guys get always loaded in the apps (except one where I am only serving a `pn.pane.Markdown`)

```
JS_SRC = "https://unpkg.com/tabulator-tables@4.9.3/dist/js/tabulator.js"
MOMENT_SRC = "https://unpkg.com/moment@2.27.0/moment.js"
THEME_URL = "https://unpkg.com/tabulator-tables@4.9.3/dist/css/"

```

If I understand correctly your answer, we actually need to modify the panel source code by adding a ` __javascript_raw__ ` attribute? I’ll try that.
