this morning when I was trying to upload some media to my web, my FTP Client kept saying the upload cannot be executed as it experienced too many retries. I tried logging in to my cPanel and found the horrible truth: I have used up the whole disk space. Aghast, I searched through the directories, trying to find which files that cost so much disk space. I found this error_log file. It consumes 150 megabytes. What is this big-sized error_log? I have googling up and down the web and found PHP codes guidance which I don't really understand. It has no extension so I can't open it to figure out myself. Is it safe if I just delete it? What's its function? It simply can't be there on my web forever! It consumes almost 75% of my dis space!
thanks in advance for the helps.
