I can not include links in the title of my blogs (Elgg 3.3.10).

I think your website is full of spammers (46k users). Install the Spam Login Filter plugging that works great.

Wogker Do you suggest any addition?

This is mostly done to make sure composer dependencies can be loaded and only for plugins which haven't been installed through composer (so zip download etc).

If you're using Elgg 3.0 or up the `vendor/autoload.php` is automaticly included when your plugin is active. So no need to do this yourself.

You must create a database and then enter the required information during the installation process, e.g. Database name, login and password.

This old video may help more (Elgg installation on Windows): https://www.youtube.com/watch?v=1kY_U3USWX0

I already set up a database for elgg...I will give that video a try and see if that will help thank you. 

I got it to work finally...figured out the problem when I first downloaded elgg it must have gotten corrupt and not downloaded all the files second time downloaded it I found it had all the files needed. Thanks this can now be closed.
