Environment

Solution

Ensure that at least the following versions installed cloudlinux-site-optimization-module-1.1-15  and alt-php-xray-0.6-20 to the latest

As a workaround, open_basedir options could be adjusted in particular domain config.  
In DirectAdmin UI go to Dashboard > Custom HTTPD Configurations > example.com > httpd.conf (3rd column)

find all lines with php_admin_value open_basedir and append at the end of each line :/opt/cloudlinux-site-optimization-module/
