http to https behavior

[muitobom]

Hi everyone,

Contao 3.5.3
I experience some strange behaviour when switching from http to https

In some browsers I see this tag and only safe content is shown
<base href="http://www.domain.nl/">

In f.e. opera the site is shown correctly and the tags is correct too
<base href="https://www.domain.nl/">

any ideas ?

Thanks

I have disabled 'Minify the markup' and this has fixed the issue. The website runs fine now in all browsers on https......odd issue

UPDATE: today the issue returned.
I now have disabled caching in the Site Structure to see if this helps...
