PHP ERRORS

HELLO, I need help here please.

I have upgraded my account with you yesterday, hoping that my issues will be resolved and you will help me with them.

Now, I have the following error message when trying to activate the plugin:

Fatal error: Uncaught ArgumentCountError: Too few arguments to

function wpdb::prepare(), 1 passed in

I solved the above errors by inserting a new “NULL” argument to each “prepare” statement in the file vlcr-setup.php.
Is that correct?
But I now have the following error:
Fatal error: syntax error, unexpected ‘wp_ajax_vlcr_get_selected_clas’ (T_STRING), expecting ‘,’ or ‘)’ in /home/185043.cloudwaysapps.com/ggztnqcaqn/public_html/wp-content/plugins/html5-virtual-classroom/vlcr_setup.php on line 1467

Apparently it is a php code issue and compatibility, I don’t know what is the reason behind these errors.

I am really having hard times here, I need to use the plugin today and it doesn’t work.

Note: I used php7.2 version, and switched back to php 7.0 and the same issue.
