Hello

I purchased today Arkhitekton theme. After successful installation of the theme, core and plugins I created simple page with short description: site is under construction. When I try to open my website, this message apperas:

Fatal error: Uncaught Error: Class "ElementorScheme_Typography" not found in /home/users/nebula/public_html/blog/wp-content/plugins/neuron-core-arkhitekton/includes/widgets/countdown.php:429 Stack trace: #0 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/includes/base/controls-stack.php(2384): NeuronElementorWidgetsNeuronCountdown->_register_controls() #1 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/includes/base/widget-base.php(1065): ElementorControls_Stack->init_controls() #2 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/includes/base/controls-stack.php(569): ElementorWidget_Base->init_controls() #3 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/includes/base/widget-base.php(192): ElementorControls_Stack->get_stack() #4 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/includes/base/controls-stack.php(314): ElementorWidget_Base->get_stack() #5 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/core/files/css/global-css.php(120): ElementorControls_Stack->get_controls() #6 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/core/files/css/global-css.php(66): ElementorCoreFilesCSSGlobal_CSS->render_schemes_and_globals_css() #7 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/core/files/css/base.php(680): ElementorCoreFilesCSSGlobal_CSS->render_css() #8 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/core/files/base.php(180): ElementorCoreFilesCSSBase->parse_content() #9 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/core/files/css/base.php(131): ElementorCoreFilesBase->update_file() #10 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/core/files/css/base.php(227): ElementorCoreFilesCSSBase->update() #11 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/includes/frontend.php(1076): ElementorCoreFilesCSSBase->enqueue() #12 /home/users/nebula/public_html/blog/wp-content/plugins/elementor/includes/frontend.php(693): ElementorFrontend->parse_global_css_code() #13 /home/users/nebula/public_html/blog/wp-includes/class-wp-hook.php(324): ElementorFrontend->enqueue_styles('') #14 /home/users/nebula/public_html/blog/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(NULL, Array) #15 /home/users/nebula/public_html/blog/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #16 /home/users/nebula/public_html/blog/wp-includes/script-loader.php(2263): do_action('wp_enqueue_scri...') #17 /home/users/nebula/public_html/blog/wp-includes/class-wp-hook.php(324): wp_enqueue_scripts('') #18 /home/users/nebula/public_html/blog/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(NULL, Array) #19 /home/users/nebula/public_html/blog/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #20 /home/users/nebula/public_html/blog/wp-includes/general-template.php(3065): do_action('wp_head') #21 /home/users/nebula/public_html/blog/wp-content/themes/arkhitekton/header.php(28): wp_head() #22 /home/users/nebula/public_html/blog/wp-includes/template.php(810): require_once('/home/users/neb...') #23 /home/users/nebula/public_html/blog/wp-includes/template.php(745): load_template('/home/users/neb...', true, Array) #24 /home/users/nebula/public_html/blog/wp-includes/general-template.php(48): locate_template(Array, true, true, Array) #25 /home/users/nebula/public_html/blog/wp-content/themes/arkhitekton/page.php(5): get_header() #26 /home/users/nebula/public_html/blog/wp-includes/template-loader.php(106): include('/home/users/neb...') #27 /home/users/nebula/public_html/blog/wp-blog-header.php(19): require_once('/home/users/neb...') #28 /home/users/nebula/public_html/blog/index.php(17): require('/home/users/neb...') #29 {main} thrown in /home/users/nebula/public_html/blog/wp-content/plugins/neuron-core-arkhitekton/includes/widgets/countdown.php on line 429

Could you please help me with this issue ?

Thank you in advance!

Best regards

Hello

Thank you for reply. I set the list of my actions because I made a lot and nothing changed. 
- Arkhitekton theme 1.3.3 - it was
- Neuron core is was 1.2.8 and still is 1.2.8 because:
- no updates available with envato market plugin
- I removed Neuron Core and install it again ( still 1.2.8 )
- I uninstalled envato market
- I downloaded fresh envato market plugin 2.0.12
- after inftallation I set new token
- still no updates for Neuron Core, moreover I couldn't turn on automatic updates feature for it
- I set also Single Item Token in Envato Market - Arhitekton appeared
- nothing changed with core updates still 1.2.8
- in my Envato Market tabs I don't see "plugins" tab

Looking forward to hearing from you.

Regards
Marcin

Thanks you! It looks that initial page works. I have to start to use Arkhitekton theme more deeply to check if everything will fine. 

For further Neuron core updates how to fix automatic updates issue ?

Regards
Marcin

Yes I know this path but it doesn't work as I described. Did you update Neuron Core to 1.3 by Envato Market plugin on my site ?

Marcin

Great, thanks!
