On wp-admin/admin.php?page=ThemesManage, if I select all websites and click Show Themes, the loading animation appears and stays there indefinitely. I reduced the number of themes one by one and tried again, and it worked when I had about 15 themes selected. More than that and it would hang.
@libbynotzoey No - it just implements a cache system built into MainWP that it can control better. Helps with specific hosting companies.
