Thank you for this great product. I am a newbie here. I installed Gregarius 0.5.4 on a LAMP stack, stock CentOS (RHEL) 4.3. Cron is handling updates. I frequently get the following errors in my logs (my domain replaced with example.com and IP replacedwith xx.xx.xx.xx). Should I be concerned? What does this mean? [client xx.xx.xx.xx] Cache unable translate to cid: http://devlog.gregarius.net/feed/?db=0.5.4-071000da7d5ac08fccb419ce9104e78c, referer: https://example.com/rss/ [client xx.xx.xx.xx] PHP Warning: Cannot modify header information - headers already sent in Unknown on line 0, referer: https://example.com/rss/ Thank you again for the terrific product. -- Sincerely, John Thomas
