Hi @therichdaddy ,
Such an error can occur due to insufficient disk space. To start with, could you please check and see if there is enough space in the server?
Another reason would be if there aren’t enough directory permissions for /wp-content/cache/wpo-minify folder. Please check with your hosting provider regarding the above aspects and see if this is the case.
Please check this doc for more info about folder permissions:

Please do let us know how that goes.
Kind Regards,
