As the installation instructions and Maverick describe, "*/5 * * * ** forms the frequency component of a line added to the crontab (cron table) file and therefore cannot be prepended to your current command. You will just get error messages all over the place.
Read the installation instructions again.
Check you are using the correct path to the cron file (the path you were given at the end of the installation process).
Check for any error messages in Etano Admin.
It seems you have two concerns.
1. Is cron running properly
2. how can I set the frequency.
Answer to 1. is that you can check three ways. First way, ask your host cron process to return an email to you on completion. check the mail for error messages. Second way, create a newsletter from Etano admin; get your "test" user to upload an image and create a blog entry then wait until your cron has executed. The uploaded image should now be visible to other users, as well as the new blog entry, additionally, the "test" user should get the newsletter email. The third way is using the "browser" version of the supplied cron file (cron_web.php NOT cron.php) together with the licence key.
Find the license key in the file
includes/defines.inc.php. and paste this together with the path into your browser address field:
http://www.your_site.com/tools/cron/cron_web.php?lk=XXXXXXXXXXXXXXXXIf it's working properly, you should see a result something like this:
time: 9:25
clean_online_table: 0 seconds
send_queue_message: 0 seconds
get_osignal_feed: 0 seconds
send_queue_mail: 0 seconds
clear_search_cache: 0 seconds
save_dot_stats5: 0 seconds
6 jobs run. I would use all of these methods to be sure.
Answer to 2. Looking at your host screen, it seems you have set the frequency at least the best you can. But you don't need ten cron jobs, just one job running each 5 minutes, if you have no choice, then set one job each five minutes and between the last one and the first will be ten minutes, I don't think it will make too much of a difference, it depends on the activity on your site.
If you're not happy with this, try an external cron host. I just searched and found
http://webbasedcron.com. It costs $25/year and you can have up to 5 jobs running as often as one minute frequency. There are others, costing more or less, some free, you choose.
Cheers!
