Blank Pages in CMS

Hi All,

I have an app I've been developing for a while. I upgraded to 3.5.1 recently, and now the Pages and any ModelAdmin's I've created get blank pages when creating a DataObject or deleting via the delete button when you edit it. No blank pages when you delete on the list view via the 'x'.

Any idea why this has started happening? I can easily enough refresh the page after it happens, but the end users aren't happy with having to create then refresh all the time.

This wasn't an issue before the 3.5.1 upgrade.

The only warning it displays in the console is: Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help

Once this happens, nothing works anymore and you have to refresh the browser to use anything in the CMS

Have you solved this issue? I am currently facing the same problem.

Hi there,

no I haven't. it's been happening probably for years now and I've just accepted that I have to refresh the page after creating or deleting anything, I use it so little on this particular system that I just tolerate it.
