This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.
Hi. Steve,
I already deactivated all plugins. I am using twenty fifteen.
And I installed wordpress again by update menu.
It’s still same.
Have you deactivated all extensions in Chrome and then used an incognito window to access the site?
Hi Steven,
I used the way, clear cache&cookie + Incognito window + disable all extention + disable all plugins + select automattic’s 2015 theme + reinstall latest one by wp’s updates.
Here are the symptom;
1.I tried on IE, and it works.
2.’Select Files’ under Media>Add New is working well
3.Browser uploader is working as well.
4.Drag and drop works fine
5.’Select files’ under Media>Library>Add New doesn’t work. This is the problem.
6.’Select files’ under ‘Set featured image’>Upload files doesn’t work.
It seems ‘Select files’ in the modal box doesn’t work.
When I click it, it doesn’t give any response. I guess it’s js problem, but console doesn’t give any message.
