Apologies! I did not receive the email notice of your post so I am just now seeing this.
re: since last upate the media librairy cannot be browse anymore. it works as a list, but it doesn’t work as thumbnail gallery.
Well, Connections does not integrate or touch the media Library in any way at any level so I do not see how Connections could affect this.
re: i have also a conflict with the plugin fsqm pro. when i try to get the results of the survey, i get a HTTP error.
I’ve never heard of or used this plugin so I have no insight on why you would have this conflict.
For both of these issues… if you can give me a temp WP admin login, I’ll take a look. The login details can be posted here as a private reply.
