The problem with styles when administering the frontend

[AnSit]

Speshitpillts and developers, please tell me how to fix another problem with the administration of VM through the frontend.

When I enter the edit mode of VM in the frontend, it seems that no styles work (see screen). It is only necessary for me to authorize once this user in the backend, as immediately all styles are perfectly loaded in the frontend. And as soon as the cache disappears, then all the styles disappear again.

How to fix this problem so that all styles are loaded normally without logging into the backend? This is very important, as there are vendors who do not have access to the backend at all and need to administer the VM from the frontend. But with such a terrible display of VMs, they are very uncomfortable and difficult to work with.

What error do you see in the browser console (F12)

[AnSit]

Thank you for your help!

[Studio 42]

I think that you use page cache ?
Change cache mode in Joomla should work.

[AnSit]

In general settings, I always disable caching completely.

Tell me where and what settings to try yet?

Do the template use a compression/minifaction for scripts ?
Jquery is not defined erro mean that jquery is not loaded, so the file missing in your HTML header.

[AnSit]

No, I don't use anything for compression and optimization.
This is the standard Protostar template.

Yes, I see that the necessary scripts are not loaded. And the reason most likely is that their download is blocking something in the VM. After all, as soon as I log in with this user on the same browser in the backend, then immediately all scripts and styles are loaded and in the frontend. But as soon as I get out of the backend and clear the cache, all scripts and styles disappear immediately and can't load in any way.

[AnSit]

If you look carefully at the errors in the browser console, then all the necessary stylesheets and scripts files are in a closed administrative folder from the frontend. Of course they can't boot. And now, just after entering the backend, access appears, they load and start working as expected. But they are stored in the browser cache. And as soon as it cleans up in time - again these style and script files disappear and everything is again incorrectly displayed in the frontend.

How to correct this serious error?

why do u say closed? Have u put an .htaccess or something in front of the admin area?

Normally scripts and css e.g. https://www.yoursite.com/administrator/components/com_virtuemart/assets/js/orders.js are accessible

[Studio 42]

Perhaps the problem can be if you filled livesite in the Joomla config ?

[AnSit]

Oh yes! I'm sorry.
Tried to open all stylesheets and scripts. Indeed, they are all accessible from the frontend.

I cannot understand in what then the problem that these style files are not applied ?!

[AnSit]

In Joomla's configuration everything is standard and properly configured.
By the way this problem manifests itself on my two different sites.
Tried three browsers, three user accounts and two different computers! It's the same problem.

just tested on a standard setup.. only the FE opened .. all JS and css load fine when using FE admin .. FE and admin scripts.
So your next step is look at the your server end. caching etc

[AnSit]

I'm not that strong in web technology yet.

"So your next step is look at the your server end. caching etc"
Tell me, please, what exactly did you mean I need to do?

Or, if I may, I could give you access to the site so that you can check everything yourself. Can this be done?

[GJC Web Design]

All I meant is that as I tested it is fine, no one else complains about this problem .. so that leaves one other source of problem unique to you -- your host..

So you need to ask them if they have any ideas as to why yours exhibits this problem ..  is the hard caching at the server, cloud flare etc etc
try switching any thing you can find off and see what happens
