Hello, I have a backup of my website on akeba solo in version 4.3.4 and it updated to version 4.4.0 and the website administrator no longer opened, it was something without style. The front-end works normally.
I restored it with the guidance of previous tickets, excluding the main folders, such as adminstrator, includes, etc... and after deletion I restored the backup. But unfortunately the backend doesn't come back. what can I do?
