Zeppelin 0.7.1 does not highlight according to code syntax - syntax-highlighting

I just installed Zeppelin 0.7.1 through HDP and Ambari and the code highlights dont work anymore. Code runs normally but there is no highlights anymore for some reason. Any suggestions what components I should look at to fix this?
Edit:
I just noticed that this problem only applies for yarn-client mode. In local mode the highlighting works fine.

pdf2htmlEX on Debian 10 for use with Drupal

There's a server migration going on, and they're moving from a Debian 8 to a Debian 10.
Everything works great except for pdf2htmlEX. The old server used v0.14.6, to which I tried to compile without success. Using the jessie package results in dependency issues, and those packages are too old and have been replaced.
I've tried with 0.18.7 and 0.16.0 (all version can be found on GitHub), and so far 0.18.7 seems to be the one working best, although some conversions result in white or transparent text (made an issue here).
As for 0.18.7, you need to compile poppler-0.81.0. I used this guide which uses 0.89.0 as an example. Compiles without error.
Is there something I am missing? fontforge is already the newest version.
Any help is very much appreciated.

why can't I see kibana in my browser? instead of it, I see the classic error 404 not found

I have been trying to instal elasticsearch with all its components; the first time it was great but I'm a beginner in in IT, so I decided unistall it to practice, them when I tried to install it again, I got the error I mentioned before.
I gotta be honest guys! I didn't know that when you uninstall elasticsearch you uninstall its components, so i tried to uninstall kibana too, but I think I deleted files that might be I've shouldn't.
this is the gui I used to install it
https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elastic-stack-on-ubuntu-18-04-es
The server has Ubuntu 18.4 and it has nginx intalled correcty.
I hope you can help me please!
Can you check these below points:
Elasticsearch is up and running
Kibana is properly configured with Elasticsearch (check kibana's configuration file)
Check Kibana logs for error
If you have covered the above 3 points and still facing issue, then please provide the kibana configuration file and kibana logs here.

Tile server for mapbox

I've tried to get this running with versions 2.14.4 and 2.15.2 without success I can run on version 2.13. I'm trying to figure out the issue, step one is as below;
In both versions this is what I see after installing the vectortile extension and restarting but this differs from the screengrab shown in the documentation. So my question is whether the documentation image is out of date or my install has not worked (2.14.4 with Vectortile extension 2.14.4).
I resolved the bug which means I can confirm that the above screenshot does mean that the vectortiles extension has installed properly

Menu is black and empty on new SonarQube 5.6 install

We do not get an issue if we install SQ5.6 on a client machine but on our Amazon servers when we fire up the server for the first time with defaults so we can install plugins, we get:
Note the black, empty menu at the top of the screen. We get this in chrome and IE11. Previous versions of SQ did not have this issue.
We have the pre-requisites correctly installed, so any ideas what could be causing this?
Thanks in advance.
Upgrade to latest (Version 5.6) using yum.
http://localhost:9000/setup
Fixed!
It does help if the browser being used is actually listed as compatible on the SonarQube site :D

jquery throbber for 1.5.2

I set out to use the ui.throbber.js plugin with 1.5.2. It doesn't officially have a 1.5.2 version, and, in fact, the version available isn't working. No throbber appears, and no errors in the Chrome console, and inspect-element shows that the javascript has run and done the surgery on the div.
I just want to start a spinner going at 'ready' and stop it when we hear back from a web service. Can someone suggest an alternative to ui.throbber.js?
I didn't find a version of ui.throbber.js that workswith 1.5.2, but I did find an alternative that will work for 1.5.2. Try nimbleLoader.
https://github.com/nimbleapps/jquery-nimble-loader
I've tested it under my 1.5.2 environment and it works and provides essentially the same result.
