These past few days there is a problem with the forum which is probably affecting most of the members. Upon logging in the forum you lose the language setting (if you don't have English as default) and the new posts. I read that the server that is hosting the forum are doing some updates and it my cause some problems on a few forums. I have opened a post in the forum host but no reply yet. Once I get a reply I will inform everyone. Please be patient and it will be fixed. For now try logging in selecting to sign in automatically.
Thank you for your understanding.
