Local content wont upload more files

Hello, Im trying to add more content to the “local content” module, it won’t let me, and the device displays on admin module : “Couldn’t write to database, You probably ned yo chmode 666 admin.sqlite and chmode 777 the web root directory”

Hi, I’m new here, you can try searching sqlite files and see the permissions

  1. find sqlite file using: “find / -name admin.sqlite”
  2. change permissions using in terminal: “chmod 666 admin.sqlite”
  3. change default folder web root directory running in terminal: chmod 777 -R /var/www/html

I’m new here but I’m interested in help with this project.
