It appears that this module conflicts with bootstrap 4 tabs like here:

There is a similar issue with "Scroll to destination anchors" which I referenced.
A solution is probably similar: exclude <a href="#"> elements that contains "data-toggle" attributes.
Fixed
1.0
Code
Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
The problem reoccurs, since bootstrap 5 has changed any data- attribute to data-bs-.
see https://github.com/twbs/bootstrap/pull/31827
Shall I open a new issue?
As far as I can see only :not([data-toggle]) has to be replaced with :not([data-toggle]):not([data-bs-toggle]) in both .js files.
