installation stops with "EspoCRM API not found"

[hotmifi]

I've tried all the suggested changes, no help.

This suggested change:
<Directory /PATH_TO_ESPO/>
AllowOverride All
</Directory>
makes my website FORBIDDEN even.

I am working with PHP 8.4 and Apache2 2.4.66 on Debian 13 and I am running a couple of websites on such configuration. Where can I find comprehensive help for this problem?

SOLVED!
The EspoCRM web directory /var/www/subd.xyz.xx -> /var/www/clients/client0/web1/ is a symlink and EspoCRM does not allow using symlink target specifications during installation. Symlinks only.
