In free hosting I tested a cron job with a file containing a delete query and having an include file
with an absolute path, and it worked fine. When I manually execute the same file, it also
worked fine. I don't understand the changed code did not work when it was manually executed.

If EasyBotter.php and cron.php files are in the same folder, the changed code should have
worked when manually executed. If your cron.php requires generating/creating something,
the permission of 'folder' and 'cron.php' needs to be set to 0777. Was your cron job not
working even if you changed the permission of both to 0777? If not working, Sogo7's
comment above might explain the reason.
