Hello everybody.
I am trying to move on another hosting with dedicated server. Now I am tuning this server. And I have a good work of all my website, but Minibb doesn't work. It shows only empty page. But when I ask for an admin page - it shows me a login page and after it - nothing. Can't understand - what could be a reason of my problem?
All new setting were made to option files.

This could mean there some critical error appears, but you don't see it (you see a blank page) because error reporting in PHP is switched OFF.

Tell me please - how to switch on PHP error reporting on the server? I use SUSE linux.

In most cases only root admin can do that, this setting (as many others as well) is under php.ini file.

I am root admin :)

Then you have a go...

Tell me please requrements to php from minibb. Which libraries I have to activate at php side of my linux server?

For the basic version you don't need any libraries at all.
Here is the list of basic requirements if you use some add-ons or extra functions.

Well...
After I have installed GD libraries from my linux distributive the forum started to work. But tell me please - why all characters that resides in database are displayed with the sign "?" ? But other staff symbols appear in a good version. The coding of mysql is UTF8

I suppose you are using Captcha which needs GD. By default, miniBB doesn't supposed to work with GD.

Symbols could mean improper database transferring.

I use Captcha and File_Upload addon :)
