I hope you can help me. Since I got the same error message when trying to update Coppermine on my domain I uninstalled it. I'm an end user on a shared server
Now that I want to install it again, I get the same error message:
"The following errors were found :
The installation package could not be found!"
What can I do? The Softaculous version on the server I'm on is 4.3.6 so it is up to date.
