I'm getting the same error for almost every action I try to complete. I can deactivate plugins but can't delete them. I can't create a backup using the BackUpWordPress plugin as it returns the following error:
php: file_put_contents(storagelocationhere): failed to open stream: Disk quota exceeded ...
I used FileZilla to download a copy of public_html and PHPMyAdmin to download an .sql backup of the database.
How should I proceed to restore my website?
Thank you in advance!
