What is generating the log?
Not sure exactly, I think it is the “general” WP debug log (it is located in wp-content folder).
I just found out that I have debug mode activated in wp-config (I activated it when I was trying to fix one plugin, I think it was for sitemaps, but I did believe I disabled it after that, guess not)
I did not read through entire log (did not want do download over 2GB, but it listed events from some unsupported function from my old theme from over 8 months ago).
I think it should be safe to delete it, i just want to be sure that nothing can go wring
Oh – you really shouldn’t have debug turned on in a live site. It creates a serious security risk. Debug is for testing/development purposes only. Edit wp-config.php and remove:
define('WP_DEBUG', true); // added to output any plugin or theme errors
define('WP_DEBUG_LOG', true); // added to output to wp-content/debug.log
Then just delete the debug.log file
