You know it would make things a LOT easier if we could
access your wiki.
OK, ngrok is running again, so the tunnel should be open for you
to view.
I figured out the problem on the Upload:Chemistry page, it was that
|addOnloadHook| was a deprecated JavaScript function that was succeeded
by |jQuery |and MediaWiki:Common.js was where I had inadvertently added
this function in an effort to customize the sidebar following this
https://www.mediawiki.org/w/index.php?title=Manual:Interface/Sidebar&ol…
guide. I have since corrected this error, and edited the MediaWiki
article accordingly.
Presently I am trying to get a self-made widget working, and trying to
decipher the errors I am getting. This widget is at Widget:Marvin (i.e.,
http://521b63dd.ngrok.com/mediawiki/index.php/Widget:Marvin) and its
implementation at User:Brenton
(
http://521b63dd.ngrok.com/mediawiki/index.php/User:Brenton). Marvin is
a Widget I hope will embed a Marvin JS applet into articles. The files
(which were downloaded from
http://dl.chemaxon.com/marvinjs/15.2.16/marvinjs-15.2.16-all.zip) are in
the |.../Marvin| directory where |...| is the MediaWiki directory where
|index.php| is, for instance. I was basing the Widget page on
https://marvinjs-demo.chemaxon.com/latest/docs/dev/embed.html as I
understand that Widgets are meant to embed HTML codes into Wiki pages.
