yesterday I ve installed two times successfully tastyignitter as described in the docs (https://tastyigniter.com/docs/master/installation). I configured and played with it without any ErrorMessage like “Missing vendor files.”
My way:
- download v3 beta to local
- extract the files
- upload to server (shared hosting)
- create MySQL db and db user
- chmod the setup-dir and includes files and folders
- run setup.php
- run through the setup-wizzard
In the SetupWizzard I choose no demo-data, and first time I checked the option to install the demo organge-theme - at the second install I choose the other option to install without the orange-theme. I installed the orange-theme by hand and the necessary extensions, too. No problem at all.
Have you test it at an other host? Perhaps the environment of your hoster is not ok? Shared hoster sometimes have some special configuration …
