Hi,
Thank you for reporting the issue, can you please mention the line number also?
It looks like this
<public_html/wp-content/plugins/wp-slimstat/wp-slimstat.php on line 219>
I wonder why you receive this error since on the previous of that line, there is a condition to check the array key
https://github.com/wp-slimstat/wp-slimstat/blob/master/wp-slimstat.php#L206-L208
Are you using the latest version of the plugin?
Yes, it is the latest version.. What’s the reason for this error?
<Top Referring Domains> slim_p1_10 Area not visible error
It’s certainly strange; I’m not sure why that happened since it shouldn’t have occurred.
I’d suggest to debug line 219 to find the issue.
