hi,
i'm upgrading from 2.8 to 3.1. after upgrading it seems that i have problem with ajax slow respond when deleting the resources. for example, when i delete resources and the click the turn editing off or clicking any other link the resources seems not deleted (but it is actually deleted as when i refresh the browser the file will be gone) and when on debugging it show undefine error.
after further check using mozilla debugging tools. when i delete resources, ajax will execute and send information to course/rest.php. The error happen while i click delete any resource and click to turn editing off/other link before the rest.php returning 200 value (rest.php finish processing).
i'm not sure what is a problem as it seems in 3.1 rest.php processing taking longer than in 2.8 (after further checking, i have no problem before as the process in 2.8 very fast)
any one know how to solve the problem? or maybe if anyway that i can have a loading bar or anything when deleting resource so that can ensure rest.php can finish the process before user moving to other page / click turn editing off?
Thanks
