I'm trying to move web site to another hosting server. After clean install of latest wordpress and unison + backup&demo content extension i press backup buttons but backup process stuck at "directory cleanup" message.
All directory and files are owned by www server user and readable/writeable.
PHP 7.1.15-1+ubuntu16.04.1+deb.sury.org+2
No any messages in error log so i have no idea how to debug this issue.
