Hello dear forumers!
I downloaded minibb 2.5a and installed it !

In options file the skin is set to default but it is different from the skin in minibb main forums

Actually I need the skin with right categories-menu and left recent topicts

Please give me advice! Thanks for the good forum system!

You need to set up the option

$startPageModern=TRUE;

under setup_options.php. It will switch to the "modern" layout.

However miniBB comes in the flat-style layout by default not by occasion. The "modern" layout will work only when you have enough topics to provide such wide-view of forums. Until your forums are not filled up with any topics, but you would like to start them right away, it's better keep the old-school schema.

However it's up to you. Fill in the forum with at least 20 topics immediately, and you'll have it.

Thank you, Paul! Great forum once again!

Thanks for the choice :) Good luck in using!
