Hi @mojowill,
Thanks for your reply.
I tried deactivating all plugins. No solution. The warning was still there.
Then, I tried to add the default theme (I deleted it some time ago without problems). When I did it I couldn’t. There was a message saying that there was an error, maybe with ww.wp.xz.cn or with the server configuration.
I don’t know what to do…
