Unable to check htaccess

I get to following error when i want to access my webapp installation:

AH00529: /usr/share/kopano-webapp/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable and that ‘/usr/share/kopano-webapp/’ is executable

This is the permission of the .htaccess:

lrwxrwxrwx 1 root root 28 Mai 31 16:58 .htaccess -> /etc/kopano/webapp/.htaccess

Whats wrong with my permissions?

this shows the permissions for the symlink.
please got to /etc/kopano/webapp
and enter “ls -la” to show the permissions on the file.
best regards

What @AnotherAndy says. In addition to this information such as the version of the installed webapp and the os are always helpful.
