annoying url slash wikidocs error

Describe your issue

I have wikidocs instaled on subfoder off another domain and when I change from subfolder to a specific folder it' crash, remove the slash on url.

I talked with host support and they told that is a a bad configuration on wikidocs and the browser use cache instead off web content.

Setup inicial example.pmt.pt -> /example_root_folder
Setup inicial biblio.pmt.pt -> /example_root_folder/biblio

I use this configuration only to use same point of FPT entry, to upload and download files. If i try to access through example.pmt.pt/biblio i receive a erro because htaccess file wikidocs as configured to root.

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ index.php?doc=$1 [NC,L,QSA]
</IfModule>

All site works fine with my 465 md files plus plus files.

Then a change the root_folder location and crash wiki

Create new root_folder to wikidocs /biblio_root_folder/
Change biblio.pmt.pt -> to /biblio_root_folder ant it break/crash with:
- some 404 error
- random errors on shash url like https://biblio.pmt.ptformacao/ instead of https://biblio.pmt.pt/formacao
- styles won't load despite being well configured

If i change all content to a new subdomain or subfolder all works fine.

This occur only in my devices and after search in internet they say the problem with cache. But notting solve

add limit's to cache on htaccess
add limit's to cache on header
change htaccess
...

I think this error only occurs on my devices, but given that it affects all my browsers and devices, I think it's strange.

Reseller support reports that cpanel is sending the files correctly, however... either they get lost or...

From what I know of how browsers work, if they do not receive the correct information, they return whatever is at hand or a random error as it was not programmed with the correct information. I point out that although there may be a problem with the browser cache... cpanel sends the correct file but along the way it gets lost... and the browser returns the error based on what you have programmed. <- - Is there any way to test this theory!?

Can you help, or it better create another sub-domain!?

Thanks
