Freshly installed WP on EC2 was not allowing me to save changes made on theme files. I followed your Bitnami WP permission video https://www.youtube.com/watch?v=nKfle7O0vN8. After performing steps on above video, I made changes on theme files and wp saved changes on files. The changes showed up right after the change.
About month after, my ISP changed my IP address when they re-plugged me to the internet.
I lost connection to EC2 due to IP change.
I followed AWS recommendation on https://aws.amazon.com/premiumsupport/knowledge-center/ec2-linux-ssh-troubleshooting/ and reestablished connection using SSH.
I made another change on theme files. Scss and php file changes were saved normally. But on browser or browser IDE, those changes don't show up. Changes are seen on files on WINSCP via SSH connection.
I have about 10 plugins related to website. None are cashing plugins, I assume. Woocommerce, mailChimp, and fbook comment plugins. I guess those plugins do not cash.
I cleared my broser both Chrome and Firefox. But changes saved in theme files do not show up and perform.
I am not so trust with your support tool. It says that it pulls whatever info that should be private.
Please help and thank you.
