• Maybe it's an issue here : https://github.com/LimeSurvey/LimeSurvey/blob/e811ff95ac71255760d973ea1142797e31755a15/themes/survey/vanilla/views/subviews/header/head.twig#L36
• {{ templateurl }} are never documented, added in 3.X : https://github.com/LimeSurvey/LimeSurvey/commit/02c6e63dd9e017c82d26d4d5bcf0bd5a8f0daa76
• "{TEMPLATEURL}" work in survey ?

So we concluded the problem is that some template screens were not migrated properly from legacy.
We are updating them.

LTS: https://github.com/LimeSurvey/LimeSurvey/pull/1924
Master: https://github.com/LimeSurvey/LimeSurvey/pull/1925

Weird, can't find the task in Zoho, despite being migrated. Will create a new manually.

Fix committed to 3.x-LTS branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=32090

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=32091

@gabrieljenik: But the fix at https://github.com/LimeSurvey/LimeSurvey/commit/77ef9e43a449691ac6ab7fb21069ec6c5cafc23a is actually not fixing the " templateurl placeholder not being replaced" problem. It just includes the image in a different way.
Did you double check that {TEMPLATEURL} is still being replaced within all twig files? I think I remember a similar problem a while ago.

@mazi:

That variable is from EM but it is not a variable in twig.

Twig gets that info like this:
{{aSurveyInfo.oTemplate.sTemplateurl}}

Thanks for clarifying, Gabriel!
