$main_column_size

Hello @arudd

Please make sure that you set the column size of sidebar at:
sidebar-left.php
sidebar-right.php

And please make sure that the conditions and column size was calculated correctly at inc/template-functions.php

Refer from original code:

if (!function_exists('bootstrapBasicGetMainColumnSize')) {
	/**
	 * Determine main column size from actived sidebar
	 *
	 * For theme designer:
	 * By using this column size, Bootstrap grid size is 12.
	 * You may change grid size of sidebar column to number you want; example sidebar-left.php grid 2, sidebar-right.php grid 3.
	 * Get Bootstrap grid size minus total sidebar grid size as conditions below this line.
	 * Both sidebar active. (12-2-3) = 7. Main column size is 7.
	 * Only left sidebar active. (12-2) = 10. Main column size is 10.
	 * Only right sidebar active. (12-3) = 9. Main column size is 9.
	 * No sidebar active. Main column is 12.
	 * Now, you write the condition above into the function below and return column size value.
	 *
	 * @return integer return column size.
	 */
	function bootstrapBasicGetMainColumnSize()
	{
		if (is_active_sidebar('sidebar-left') && is_active_sidebar('sidebar-right')) {
			// if both sidebar actived.
			$main_column_size = 6;
		} elseif (
				(is_active_sidebar('sidebar-left') && !is_active_sidebar('sidebar-right')) ||
				(is_active_sidebar('sidebar-right') && !is_active_sidebar('sidebar-left'))
		) {
			// if only one sidebar actived.
			$main_column_size = 9;
		} else {
			// if no sidebar actived.
			$main_column_size = 12;
		}

		return $main_column_size;
	}// bootstrapBasicGetMainColumnSize
