Files/folders not created any more

Hi,

I use the plugin for 3 years without any issue, but I suddenly have a strange behavior: I can no more create folders or files… When I try to upload a file, I got the following message (in French):
“Désolé mais xxxx.jpg n’a pas pu être uploadé.”

I didn’t change anything in the WP rights or plugin configuration before the problem occured.

I first thought it was due to disc quota full. But this is not the case (I can add files through FTP and have several GB remaining). Then, I thought it would be folder right issue on the server. To test, I created a folder with rights 777, but this didn’t change anything.

If I try to create a folder, there is no error message, but the folder is not created.

I updated the plugin and WordPress to the latest version, but this didn’t solve anything.

Does someone have an advice how I could debug that and try to understand where the issue is ? Many thanks for any suggestion….

Cheers.
