I have tried updating my installation using the softaculous app installer. it gets to 95% then says “oops we have lost connection” and it hangs there and then fails. I have tried this on different ISP’s and connection ways but the result is the same.
I have tried with the backup option turned off and on.
Under the task list of softaculous it gets stuck on 15% with saying:
“Upgrading Invoice Ninja
Copying files and folders”
I actually solved this another way.
I read on another forum that sometimes the web browser causes the update not to go through.
I was using Firefox so i switched to chrome and tried the update and it completed successfully.
Hope this helps someone else in the future. Just try a different browser because some softaculous update scrips only work on some browsers…
