The site is currently in version 5.5.1 and I stick with all WP and plugins versions to “latest and greatest” as soon as possible.
Recently I noticed that:
1. In the site root folder I have a rather new file (created a few months ago) named error_log; and it is the actual error log file that is being filled, while the “old” error_log file is not being updated with any new events
2. The same happens in /wp-admin (I didn’t even know this folder has such any error_log file)
3. Both the error_log; files, as mentioned above, get filled with mostly what looks like the same events.
Where all of this came from? why?
