Running 1.1.13, modified a bit :)
Never had any Cannot modify header information - headers already sent errors in my logs, until yesterday through today when a bot from 199.15.234.78 (listed as owned by a server company) visited. Many errors, every page hit, but only from this IP, no other user - ever. Also had session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cache limiter - headers already sent and session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cookie - headers already sent errors by this IP, unsure why the HREF thing. Anyone know what is going on here? I blocked the IP range in htaccess, but I wonder why it happened. Thanks.
Can't think of any exact reason to this, if no one else has ever caused such errors...
...and nobody has since. I just figured I'd ask in case I had fouled up something. Thanks.
