Hi everybody

I'm having troubles with incoming mail servers. In fact, sometimes, they just don't fetch their mail. Therefore, I wanted to delete a server but it doesn't work. 

If I go on settings > technical > email > incoming mail servers, I select a mail server and click more > delete. 
OpenERP starts to load and never stops. I need to reload the website and the server is still there. 

OpenERP: V 7.0-20140804-231303
OS: Ubuntu 14.04 LTS
BD: PostgreSQL 9.3.5

Can anybody help?

best,

bertrand
