I also had this issue. When I entered Media in dashboard I got “infinite” loading. The source of it was my plugin that i developed. I found out that my plugin also load in a page ‘admin-ajax.php’ and that was the reason.
When I stop my plugin from load in this page using the next code:
global $pagenow;
$excludePages = array(
'admin-ajax.php',
);
if ( !in_array($pagenow, $excludePages) ) {
[load my plugin]
} else {
[only load my admin menu link]
}
and after that the “infinite” loading has stoped.
Thank you for your comment Jan. I think my previous comment has useful information considering the fact that we are presenting some new concepts. Expecting all viewers to visit our website for doing some “extra reading” would not be wise. Therefore bringing some basic information and let user get familiar with our service through a comment that is associate with our own plugin page seems to me as a good idea.
