Install C5v8 almost from scratch
I never made it to upgrade C5 to 18.104.22.168, so that I could use my new theme. Since it is a private site to learn Concrete5, I thought I might as well delete all and try to install the new version 8 manually (most bugs should only be upgrade bugs?). Server was first downgraded, but I upgraded it again to run PHP7 (should work?).
Here is what I did:
1. Via my host I reset the current database.
2. Via FileZilla I deleted all files and folders within the public_html folder.
3. I have the unzipped v8 on my desktop, so via ftp FileZilla I upload all folders and files in the public_html folder.
4. I go to my webpage and find attached error:
I found a Stack Overflow question that sounds related to this:
I looks like an issue on the server, so I need to go my host?
I recommend contacting your web host support regarding this,
I was sure that C5 v8 was optimized for PHP7, but my host told me to downgrade to PHP 5.6, and then it works this time.
