Issues with error messages

[victorgrant]

Hi,

While trying to install version 8 (the current version on your website) I was directed to all sorts of configuration files and I also got frustrated because none of the stuff was the same when trying to do stuff like add a user etc. That's when I went to the version 7 mentioned above. I was able to install that easily and also create the necessary database, etc, but I got error messages/warnings on the front page of the created website and when I used any of the administrator menu items to whit: count(): parameter must be and array... and Deprecated function: the each() function is .... I got rid of these messages by turning off all warning/error messages under the configuration menu. What I can't figure out is if this stuff is because I did something wrong or because there is a flaw in 7.57. Can anyone enlighten me?
Please help.

I didn't find the right solution from the Internet.
