Hi Vijay,
I have fixid this spinning issues before you need to try deactivate/Active all your wordpress plugins, after the follow steps:
Go to this page(template-builder.class.php) located at : /themes/enfold/config-templatebuilder/avia-template-builder/php/template-builder.class.php goto line 187 or find script
wp_enqueue_script(‘avia_element_js’ , $this->paths[‘assetsURL’].’js/avia-element-behavior.js’ , array(‘avia_builder_js’), $ver, TRUE );
Comment this line
//wp_enqueue_script(‘avia_element_js’ , $this->paths[‘assetsURL’].’js/avia-element-behavior.js’ , array(‘avia_builder_js’), $ver, TRUE );
And go to wordpress browser refresh your page where you caught error(continues spinning) in dashboard editable page. after refreshing the page it will loads the page without spinning, and again uncomment script line(revert back what changes done) and refresh again then you will load editable page without continues page spinning.
