As my VPS was running out of disk space, I deleted some .tar and .zip files of which I thought they were old backups.
After deleting a specific .tar file however, I get this error on the front-end of my Joomla site : 404 - PLG_SYSTEM_REDIRECT_ERROR_UPDATING_DATABASE
The back-end of the installation still seems to fine.
Although I can not understand how a Joomla site can be dependent on a .tar file in the root of the server's HTML folder, it seems to be the case.
As I have no experience with VPS, I would rather not take any more chances and leave it to an expert to retrieve the file back and hopefully get the site going again.
I would also need some maintenance done on the VPS and the Joomla installation.
It seems to me that there are several obsolete database instances using up my disk space but obviously this will need to be verified and cleaned up by someone who knows what he/she is doing.
This is quite urgent as I need the site online asap.
Looking forward to some valid responses
