Installation - Fatal error

Hi,
I have problem with installation. I get something like this:

Warning: set_error_handler() expects the argument () to be a valid callback in /home/eh147442/public_html/weboom.info/vendor/symfony/var-dumper/Dumpe r/AbstractDumper.php on line 91

Where is the problem? Thanks for help.

What version of PHP are you running?

5.4

How did you install Grav? Did you use a skeleton, or the basic Grav package? What were your steps to 'install' as it's only a zip file that you just extract.

basic Grav package, I only extract files on FTP

It's a very strange error, it's almost like your zip was corrupted, or your missing files.

I try download zip several times and extract it many times on two diffrent hostings

Ok - it was hosting problem. Thx for help :)

@vick0019 What was the hosting problem/fix? I have this same error coming up.
