For some reason, one of my two installations of LimeSurvey does not save at all the theme options, neither from within any survey nor globally. It does, however, show the message "Theme options saved". It seems, also that in the nav_bar.twig, the following line does not point to the correct file address:
{{ image(aSurveyInfo.options.brandlogofile, aSurveyInfo.name, {"class": "logo img-responsive"}) }}

I had to specify the file as follows:
{{ image('./files/logo.png', aSurveyInfo.name, {"class": "logo img-responsive"}) }}
However, this is not a good solution, since the application refuses to save (and display) any different logo, specified in the surveys.

Any suggestions?

Thanks

Some other strange problems appeared in this installation: the sidebar of the "Configuration/Global survey" menu is empty. I suspect that there may be some problem with this specific installation, perhaps related to some settings or config files. Is there any way to repair the settings without affecting the surveys already stored in the system?

About the white part : check if you have error in console.log of your webbrowser, and check with another browser too.

About the logo : maybe report the issue ?

Thanks again for your response. I have checked with another browser (and with another installation). And the problem with the blank menu appears also there.

I do not know how to access console.log.

F12 on browser
duckduckgo.com/?q=javascript+console++browser&t=ffab&ia=web

OK (thank, again!). When I get to the "Configuration/Global survey" page, I press F12. I then see the Console referring 2 errors:

1. Failed to load resource: the server responded with a status of 404 (Not Found) roboto-v18-latin_latin-ext-regular.woff2:1
2. Failed to load resource: the server responded with a status of 404 (Not Found) adminbasics.min.js:1

Beneath those, there is this message:
AdminCore Triggering panel animation

Is this info relevant?
 

> Failed to load resource: the server responded with a status of 404 (Not Found) adminbasics.min.js:1

I think it's an issue here : try to reset asset cache (in Global settings/general)

Please update to 5.2.2 where the menu issues should be resolved.

Thanks for the reply. I already have updated LimeSurvey to 5.2.2. Unfortunately, the "Configuration/Global survey" problem with the blank menu persists.

(As well as the problems with not saving choices in theme options)

Finally, the problem with the missing menus was solved by resetting the survey menus and the survey menu entries. For some reason, a new custom menu appeared in the survey menus tab. It had to do with the plugins.

The theme options selected by the user, keep disappearing though.

It seems that depending on the theme version, different problems appear. I managed to narrow down the problem with theme options not saved in the configuration described at the end of this message.

With the Fruity theme, the only option that is impossible to save concerns the images (logos, backgrounds, etc.).

Case 1: Theme options (global level)
When I select (or upload) some image, its filename appears in the corresponding field and the "Preview image" button works just fine (screenshot 1).
Upon saving, however, the filename disappears from the field and the theme acts as if no logo is selected (screenshot 2).

Case 2: Theme options (survey level)
When I select (or upload) some image, its filename appears in the corresponding field and the "Preview image" button works just fine (screenshot 3).
Upon saving, however, the filename disappears from the field and the theme acts as if no logo is selected (screenshot 4).

Other options are saved correctly, though (e.g. "Variations", colors, etc.)

Hello there,

I thought I was an idiot trying to save a simple theme logo for like 30 minutes. Also not able to save a chosen image in any extended theme. Fresh installed today of LS 5.2.4+211129. PHP 8.1.
Can upload and preview images without issue. Can even save other theme options. Both global and children adffected.

Choosing a freshly uploaded image file and saving does not stick even though LS reports saved successfully.

Is this LS 5.2.2 version beta? Should I be using good ol' LTS 3.27.27 instead?

Regards
