Why I can not see the graph (Line or Bar) on my site? Is it the problem of server or program?

mark’s comment is a nice solution.

try input the url directly on adress bar.
https://your.site.dns/wp-admin/index.php
or
https://your.site.dns/wp-admin/post.php
I’m not sure if it works.

it is under \wp-content\

Try the plugin : page-navi
I installed it yesterday, and it is working well.

I tried PHPMyAdmin, but it didn’t work well, maybe due to the PHP configuration or MySQL version on hosting server.
But this tool deal with it very well. Thanks.

I downloaded it, uploaded it into /plugins/, and actived it, and add a line to call page_navigation(), but nothing happened. Could you tell me why? thanks.
