Login problem

sorry my english, I know is not well.

I am running a PBX in a flash system and I am having problem login in via web.

When wonking fine i can log in using maint user as admin but from now on I am only prompted to enter a password. I tried entering the maint user pwd but do not work.

any clue?

it seems that the change happened after an update. I did update-scripts and update-fixes but nothing has changed.

thanks in advance,
