Hi!
I doo: it says LimeSurvey Version 3.16.0+190225 at the right hand bottom of my account. I wrote template.css because I read it a lot in Forum comments and thought it still existed. That´s quite a good demo of how i often don´t get whether something is just something i don´t understand yet, or simply part of an older limeSurvey version. ^^
Re ideas + results:
Maybe I explained it badly, but for one I cannot change anything in source code of templates themselves, because i don´t have administrative access. I can only access the options at the bar at the top right side of the screen (see tiny picture).

That means I haven´t tried option A. (Just read about in in forum.)
Option B ) (which was displayed as

in my last post), is something i thought might work without using java or actually changing the original template (which cannot be changed since others at the uni use it too). That is, the .languagechanger order.
I did try to ask my super administrator to make a template copy and turn it off in there, but I´m not sure how well she goes about limesurvey because she suggested to simply x out the second languge under additional languges in general settings - something i cannot do, because the default language is German. But this is also the language I`d like to hide, as my survey will be in English only.
So that left me with wanting to tryout
.languagechanger {display:none;} as suggested here by holch and tpartner but I just don´t get where to put
slash if i can´t put it anywhere because i don´t have administrative rights.
I did simply try putting it in the Files CSS, but was told about 10 times:
Error: Malformed JSON: Field files_css must be either a JSON array or the string "inherit". Found "". If I put it in Files Print CSS, it doesn´t give warnings but also doesn´t remove the switch. Same for putting it in Cssframework Css.

Possible explanations
1. it was never meant to go in the advanced theme settings in the survey,
2. code is wrong or outdated (missing brackets, other signs..),
3. order correct but some setting missing in order for it to work,
4. ???
There´s so much help and input in manual and forum (which is so cool! thanks) but I lack a feel of which order can go in what setting and how/if I´d have to modify forum suggestions for older lime versions. Like when you learn vocabulary but get the grammar all wrong

- I´m not asking you to do my grammar work though, if that came out wrong.
Does that make sense? (Sorry, I suck at keeping it short.)
Thanks:)
