Hi,
I receive a “non blocking error” when trying to copy an existing page on my wiki hosted on myxwki …
It’s not blocking because at the end the new page is available but Thomas Mortagne 
seems to encounter some difficulties running my wiki …
Please find hereafter an extract and please find the full stack trace here : https://pastebin.com/5gddrLtA…
