Hello Support Team,

Two days ago I bought this theme which looks very nice. For the test version I have installed it on a subdomain: https://minisel.rapid.si/ , where I managed to see that there is some error. I successfully import the demo content, but what I managed to see that there is an error with elementor, here is the code: 

• Fatal error: Uncaught Error: Call to undefined function Elementormb_strtolower() in /home/rapid/minisel.rapid.si/wp-content/plugins/elementor/includes/utils.php:650 Stack trace: #0 /home/rapid/minisel.rapid.si/wp-content/themes/soledad/inc/elementor/includes/helper.php(281): ElementorUtils::parse_custom_attributes('') #1 /home/rapid/minisel.rapid.si/wp-content/themes/soledad/inc/elementor/modules/penci-simple-list/widgets/penci-simple-list.php(466): penci_el_get_link_attrs(Array) #2 /home/rapid/minisel.rapid.si/wp-content/plugins/elementor/includes/base/controls-stack.php(2321): PenciSoledadElementorModulesPenciSimpleListWidgetsPenciSimpleList->render() #3 /home/rapid/minisel.rapid.si/wp-content/plugins/elementor/includes/base/widget-base.php(634): ElementorControls_Stack->render_by_mode() #4 /home/rapid/minisel.rapid.si/wp-content/plugins/elementor/includes/base/widget-base.php(775): ElementorWidget_Base->render_content() #5 /home/rapid/minisel.rapid.si/wp-content/plugins/elementor/includes/base/element-base.php( in /home/rapid/minisel.rapid.si/wp-content/plugins/elementor/includes/utils.php on line 650

I have tried to delete and install the Elementor again but the error persists, so maybe something is not compatible.

Thanks i have access to the cPanel and I install 'php-mbstring' extension

now everything works perfectly
