PHP Warning: Cannot modify header information - headers already sent in Unknown

Hello all.

Just loggin in Roundcube gives 2 of those errors in the error.log...

Using various functions around gives some more of them...

Any idea?

That error is common if there are extra CR's or spaces before or after the PHP script. Make sure you have no trailing spaces/returns on the config files. Did you open/edit any other files?

That is probably the first thing to check...
