Am doing a fresh install of Tiki 15.2 and will be upgrading a 12.2 database. But when I try to install, I just get the following error message:
"Your Tiki is not completely installed because Composer has not been run to fetch package dependencies. You need to run 'sh setup.sh' from the command line. See https://dev.tiki.org/Composer for details."
I cannot do what's suggested on a shared server, which is how I've always run my Tiki installations. Is there no way to avoid this issue?
