Error while suppressing a file

I run oc 10.0.3 and I ùight have broken something :
What I did : I started to upload files in the folder "Photos Beterette"
in the meantime, on another window, i pressed this folder's chain in order to give a public access to it. Changing my mind, I did'nt proceed.

Anyway, I get the message "Error while suppressing a file" while I try to delete "Photos Beterette" folder.
Is there anyway to get rid of this folder that I don't need anymore.

Here is the log :

I suppose you have no redis server.

You can either wait for 1-2 hours until the cron job kicks in and deletes the file locks.

Or you can manually remove the locks, you have to login to you database, I suppose you have mysql, switch to your owncloud database, and execute truncate oc_file_locks;

Thank you for your answer
However, I executed truncate oc_file_locks and got the same error message again

is the file_locks table empty?

can you restart the mysql and apache2 service?

I might have done something wrong :
the file was not empty rigth now. I re-executed the command and upload worked perfecrly.
Thanks for helping

You're welcome, great to hear that this worked
