Hi themeco,
In screen error is cryptic and hard to discover what is at fault. The browser console offers:
app.react18.7.4.8.js?ver=7.4.8:28 Save Error for document: Error saving content elements: Unable to save content: 0
(anonymous) @ app.react18.7.4.8.js?ver=7.4.8:28
app.react18.7.4.8.js?ver=7.4.8:5 Failed to save Error saving content elements: Unable to save content: 0. Error: Error saving content elements: Unable to save content: 0
at US (app.react18.7.4.8.js?ver=7.4.8:28:26314)
at async app.react18.7.4.8.js?ver=7.4.8:28:29567
DO @ app.react18.7.4.8.js?ver=7.4.8:5
And there’s nothing to be found in the Apache http error logs
