After the release of beta 1.12, this was the first time I tried to change the CSS loading method. So, I changed external files to inline css and the settings saved fine. But now when I try to change it back to external files, the settings are not saved at all and the admin ajax error is displayed in the browser console.
I can reproduce this constantly. All plugins are disabled.
When will the problem be solved?
When I disable all performance settings and then change the CSS loading method to external files, the problem is resolved.
Of course, if I repeat this cycle again, saving the settings again will be problematic.
thank you for the report. Locally, we already solved this issue, so it should with next update
I’ll link this topic to the task, so we can update it once we release the fix.
Now, I think if you disable cascade layers, and try to save it, it should work. I don’t think you need to disable all settings.
