Thank you kmessinger for replying,
– yes, I deactivated all plugins, and the problem remains.
– I switched to Twenty Eleven theme, and the problem remains.
I have 11 plugins all deactivated right now and the problem is still the same.
Do you suggest I delete them all? I would have to re-configure some of them… About the FTP you are talking about, I am not sure what to do… I see the 11 directories for each plugins in wp-content/plugins, but what should I do with those? Delete the files then put them back in?
Thanks for your help,
Annie
