Answer 1

Rights issue?

Answer 2

You need to make sure that the files have the same owner as the Apache user. In addition, set the necessary rights to folders and files.
For mass change of ownership, you can use:
Here is a universal solution:

cd /home/bitrix/www
find . -type d -exec chmod 775 {} \;
find . -type f -exec chmod 664 {} \;
find . -type d -exec chown bitrix:bitrix {} \; 
find . -type f -exec chown bitrix:bitrix {} \;

/home/bitrix/www — directory where the site is
located bitrix:bitrix — user and group under whom the httpd daemon is running
Users and groups can be viewed in phpinfo.
