Creating one topic for multiple issues is not the best practice and it will end in general answers. 😉
- I think you’ve seen already those 2 are different. The Tiki official package release (with vendor files) that should be used for production sites and the Tiki development files (requires more operations to install) that should be used if you want to contribute, modify or test. While you can use the version distributed on Gitlab for production you have to be aware that it is different and requirements are not the same.
- If you find some files that shouldn’t be included it is good to tell it here, but better to create a bug report. If security is involved reports to security at tiki.org.
- If you want to start a Tiki project from official release use : https://tiki.org/Download
- If you want to start a Tiki from Git (we use Gitlab) you can use:
git clone --branch=21.x --depth=1 https://gitlab.com/tikiwiki/tiki.git Tiki21
git clone https://gitlab.com/tikiwiki/tiki.git .
Then follow the instructions. 😉
Hope this helps
