• the error seems clear, what do you think $log is ? you can check with var_dump($log)
• get_log() isn't returning what it's supposed to be. You need to check that function and see what's going wrong there. If you add some other code to only check the count if $log is countable, you may end up covering up a problem rather than solving it.
• Hi thanks. I tried this fix but I still get the error and can't save the form page
• When i use radio buttons I'm able to save the page. But when it's the select/dropdown field the error comes up
• Please add form html in your question?
