I was coding my site on Apache Server. Suddenly an error came and I got the warning
This computer has only 1.3 GB remaining.
I knew that this was because of the log file in /var/log/apache2/subins/error.log.
I opened the folder in root and the file size of the log was 17 GB. I deleted the error file. I went on to the root trash folder to delete the log file permanently. I deleted the files and info folder in the 'root trash' folder. So I had erased the root trash folder. But things got wrong. I still get the warning
This computer has only 1.3 GB remaining
I think I did the wrong way to empty root trash.
I used Disk Usage Analyzer to find the log file to permanently delete . But the software didn't showed the file. What happened to the folder I deleted in 'root trash'?
Here's the screenshot of Disk Usage Analyzer after the search.
UPDATE: Now my computer memory is 1 KB after I run the web page again in which the error showed.
