Could you send us the steps for reproducing the issue? Install All in One SEO + Litespeed plugin. I see a log file: wp-content/all-in-one-seo-pack.log I dont know if Litespeed and AIO SEO conflict and cause down performance when these plugins depute to output handler The Litespeed report number I already give. LiteSpeed Cache likes most of other WordPress caching plugin which modifying the output before sending out. The log you show is just explaining AIO SEO detected our output handler and it should not affect the performance. AIOSEOP dev here. I can confirm that what youre seeing in the log is simply a notice that LiteSpeeds output buffering was detected, not that theres any actual problem from it. Unless youre experiencing a problem, you can safely ignore the notice. We typically recommend having logging off on production sites unless youre encountering a problem. Thanks for clarification @hallsofmontezuma!
