Error importing data to Travelift

I have used the Customize Export/Import several times to create copies of my development site for testing purposes. Each time I have installed the Travelify theme which works just fine.

The last time I tried to import the exported datafile (travelity-export.dat) I got the following error:

Fatal error: Uncaught TypeError: Unsupported operand types: string * int in C:\Users\gregj\Local Sites\gafia\app\public\wp-content\themes\travelify\library\functions\functions.php:96 Stack trace: #0 C:\Users\gregj\Local Sites\gafia\app\public\wp-content\themes\travelify\library\structure\header-extensions.php(142): travelify_pass_cycle_parameters() #1 C:\Users\gregj\Local Sites\gafia\app\public\wp-includes\class-wp-hook.php(324): travelify_headerdetails(”) #2 C:\Users\gregj\Local Sites\gafia\app\public\wp-includes\class-wp-hook.php(348): WP_Hook->apply_filters(”, Array) #3 C:\Users\gregj\Local Sites\gafia\app\public\wp-includes\plugin.php(517): WP_Hook->do_action(Array) #4 C:\Users\gregj\Local Sites\gafia\app\public\wp-content\themes\travelify\header.php(69): do_action(‘travelify_heade…’) #5 C:\Users\gregj\Local Sites\gafia\app\public\wp-includes\template.php(790): require_once(‘C:\\Users\\gregj\\…’) #6 C:\Users\gregj\Local Sites\gafia\app\public\wp-includes\template.php(725): load_template(‘C:\\Users\\gregj\\…’, true, Array) #7 C:\Users\gregj\Local Sites\gafia\app\public\wp-includes\general-template.php(48): locate_template(Array, true, true, Array) #8 C:\Users\gregj\Local Sites\gafia\app\public\wp-content\themes\travelify\index.php(8): get_header() #9 C:\Users\gregj\Local Sites\gafia\app\public\wp-includes\template-loader.php(106): include(‘C:\\Users\\gregj\\…’) #10 C:\Users\gregj\Local Sites\gafia\app\public\wp-blog-header.php(19): require_once(‘C:\\Users\\gregj\\…’) #11 C:\Users\gregj\Local Sites\gafia\app\public\index.php(17): require(‘C:\\Users\\gregj\\…’) #12 {main} thrown in?C:\Users\gregj\Local Sites\gafia\app\public\wp-content\themes\travelify\library\functions\functions.php?on line?96

As far as I can tell, the import was mostly successful, except for this error. I’m using version 3.0.8 on all the test sites. I’m wondering if anyone has any idea what caused the error message?
