I have been running Akeeba Solo successfully for one site, but since a couple of weeks, it's having issues transferring the files to Azure.
I have accessed to the manage backups area and in release 7.6.0 and also after updating to 7.7.0 when I click the button Transfer Archive (Azure) I get the following error message:
Error: Class "Akeeba\Engine\Postproc\Connector\Azure\Blob\Instance" not found
I think the problem is not related to the post-backup send to Azure process so I also link the log for the latest backup which was not transferred to Azure
The log file for my last backup is here (taken when still in 7.6.0):
Any idea on how to fix both issues?
