How to modify the character limit

I want to use one character as a blog title, how to put "pleses specifty post title (from 3 to 255 character)" into "pleses specifty post title (from 1 to 255 character)"?

look for something like this in the page or block builder. hope it helps.

Additional field's properties (Advanced tab):

Control. Available only for the fields with Selector and Multiple-Selector types. Defines an HTML-element for displaying in forms.

Mandatory. Defines if the field is necessary on the page. For example, NickName is a required field.
Such fields are marked with red stars next to field's title and are checked if they contain any values.

Minimum value. It defines the minimum value of the field. For text fields and passwords it defines the minimum number of characters to input. For numbers it defines the minimum number. For the fields of Date type it defines minimum age.

In case this field isn't filled, there will be no limitations.

Look for this at about line 1839

            'inputs' => array(
                'PostCaption' => array(
                    'type' => 'text',
                    'name' => 'PostCaption',
                    'caption' => $sPostCaptionC,
                    'required' => true,
                    'checker' => array (
                        'func' => 'length',
                        'params' => array(3,255),
                        'error' => $sCaptionErrorC,
                    ),


Change: 'params' => array(3,255),

To: 'params' => array(1,255),
