What really scares me is that due to such a small mistake as disabling the language the forum is not running well for a few days now.
If Flarum leaves the beta status and more users like me (without experience with PHP, code, etc.) use Flarum, so "errors" should be much faster and easier to fix.
The link to the "extiverse helper" makes me belly ache, still all post and images are available in the forum, I have the fear that they will no longer be there after running.
The instructions are hard to understand... at least for people who have no idea about it, I did not understand why the instructions for the installation can be found only in the middle of the text, I already thought they do not exist :-)
