Disaple app from cpanel file manager or ftp

I made some misconfiguration and I need to disable onlyoffice and community server from
my cpanel because I installed it in shared hosting and i do not have ssh access

My nextcloud is not loading at all after installing onlyoffice so have to way to go to apps and disable it there.

You could try this. Instruction set for apps — Nextcloud latest Administration Manual latest documentation

You might also be able to download the config file, disable them app, and upload it. Be very careful with syntax, line endings, and permissions if you try this over FTP.

Thanks I know how to handle permission , I prefer to do it in config file
Where is it?
