Update failed

Hello,

The update of all-in-one event (version 2.6.3) failed on my Website on this morning. Unfortunately, I did not notice the error message. Now, the calendar is no more available and the extension does not appear in the list of installed ones. I tried to re-install it but it also failed because the directory is still on the server.

Please, could you advice me ? Should I remove the directory ? Will I lose my data if I do this ? Should I try to re-install the previous version that worked ? If so, where I could find it ? Thank you.

Notice, I’m not very expert.

Best regards,
Pierre Blouch
