Devon:Thank you for replying to my query. This has been an ongoing issue and since we have 18 iPad2s here with us as our platform for using Kolibri and KA Lite, we’re kind of hardware stuck. I’ll give you all the details and what I’ve seen:
iPad2s: running last supported iOS 9.5.3. Have tried last supported version of Firefox (8.3 (5826), as well as last supported version of Chrome (63.0.3239.73) and MS Edge. Same problem across all of these browsers. Safari won’t load Kolibri because is not supported.
I did more testing yesterday. iPad Air 2, both running latest versions of iOS and the browsers - all work fine. Also, KA content works fine on Mac OS Safari, Chrome, Firefox, etc. I don’t have an Android-based device to test. I have tested with my MacBook Pro and a Win10 laptop. No problems with content delivery on these.
So, the problem seems to be limited to our iPad2s. I’ve found that the Early Math content we are working with proves to be hit and miss, particularly with exercises with graphics and large colored text. I’ve seen that it is showing up throughout all the early math exercises where graphics sometimes load, and often don’t.
I have seen this is the case with both the updated KA Lite content inside Kolibri and the current version of KA Lite. Yet, all of the same content coming directly from Khan online works without a problem.
So, could this be an incompatibility of Nginx and the version of iOS on these older iPads? I thought about trying the Apache-based install of KA Lite as described on the installation options to see if that could make a difference, but that would not solve the Kolibri issue. I’m really hoping there can be a fix for this as this is making our plans to implement difficult to realize w/o having to look at a major hardware purchase expense that is not in our budget.
thanks for your help!
