hi, im usung ubuntu 18.04LTS with ispconfig 3.1.15 and i have been having some issues with file ownership on a wordpress based website, for example: files uploaded to the server via ftp are owner:cliant1 group:web1 but file genrated by wordpress itself are owner:www-data group:www-data, this is an issue because yes the files maybe readable (sometimes) but some tmp files are not modifable because of ownership confiits. please advise
You are using a wrong PHP mode or you missed enabling the suexec checkbox in the website. PHP mode for content management systems like WordPress must be php-fpm or php-fcgi and the suexec checkbox in the website settings must be enabled.
