Yes,

It's the only one with InnoDB …

No strong opinion about the best.

Check the pull request : github.com/LimeSurvey/LimeSurvey/pull/1043

Ok, I've talked to my hosting company and they approve what I saw in phpmyadmin and said the innoDB is ok and enabled.
So how do we fix this?

p.s.
Solved it now.
Changed the "database name"/"host name" from localhost to the one I had.

So now I have left with one thing that I don't know what it does.
I saw in the "STEP 3 - Pre-installation check" that I don't have "php LDAP library".
What does it do and how can I get it?

LDAP is a directory service. When you don't know what that is, you don't need it for LimeSurvey. Just continue.

Changed the "database name"/"host name" from localhost to the one I had.

Oh, you really should learn some basics when installing on a web server.

I don't think it's that...
They give different names to same things.
I always get confused with this.

Can I make a "Pre-installation check" after I've installed LS?
Because I've seen some red icon when I talked to hosting company, but I think the red icon was because I have been waiting for long time.

I think it was something about temp directory.

Can I re-check it somehow?

No, but I suggested that as a feature last year.

Cool.
I remember I've made a "phpinfo.php" file.
Is it the same or something else?

<?php
phpinfo();
?>

phpinfo is showing you infos about the php environment. The LimeSurvey installer compares the environment to the requirements and recommendations.

You will miss the red icons you're looking for.
If you want them badly, just install LimeSurvey again.

Don't know where in the forum to put this problem.
There are 2 pages here in this post, but when I click page "2" it never goes to it.
It stays in page "1".
I'm able to go to page "2" only by my email I've got from the replies.
Are you also experiencing this problem?

What???
I see this.

So I am on the second page.
Clicking the first page shows your very first post about "InnoDB" and "myisam".

And the second page starts with Denis' answer "Yes".

So what are you talking bout?
