Master Slider is causing errors on my site

Hi,

I got an email that Master Slider is causing a fatal issue on my site. So, I tried to access my dashboard to check but I could not. I contacted the host and they deactivated the plugin and the dashboard loaded again.

Here is the error they sent me:

1 PHP Fatal error: Uncaught TypeError: Unsupported operand types: string / int in /nas/content/live/thenfrw/wp-content/plugins/master-slider/admin/includes/msp-admin-functions.php:232\nStack trace:\n#0 /nas/content/live/thenfrw/wp-content/plugins/master-slider/admin/views/setting/class-msp-settings.php(277): msp_get_pro_users_num()\n#1 /nas/content/live/thenfrw/wp-content/plugins/master-slider/admin/views/setting/class-msp-settings.php(34): MSP_Settings->get_settings_fields()\n#2 /nas/content/live/thenfrw/wp-includes/class-wp-hook.php(310): MSP_Settings->admin_init(”)\n#3 /nas/content/live/thenfrw/wp-includes/class-wp-hook.php(334): WP_Hook->apply_filters(NULL, Array)\n#4 /nas/content/live/thenfrw/wp-includes/plugin.

Note:

I had some heavy auto-loaded data a few days ago, so the hosting agent sent me some values that I should set to No. Some of those values are related to Master Slider. Here’s what I set to no:

| _transient_master_slider_output_1 |
| _transient_master_slider_output_2 |
| _transient_master_slider_output_4 |
| _transient_master_slider_output_9 |
| _transient_master_slider_output_3 |

I’m not sure if this has anything to do with the problem. Could you help and tell me what to do?
