I am using version 4.5.2 in a shared hosting environment. When I try to configure the site as admin, I usually need to click two or three times on the relevant configuration section (e.g. products or categories) before the table rows are displayed. The buttons are often not responsive to my input. I am running with 750 MB of RAM and as per my host, RAM is not the issue. Any suggestion of why I am having this problem? Thank you!
