Chron not working correctly

[windwriters]

Hi

I am running a WordPress Blog version 2.9.1

I installed the WordPress Plugin Thank Me Later and I am getting an error message:

WP-Cron doesn't seem to be working. Thank Me Later is emulating the behaviour of WP-Cron, which may slightly slow down some page loads. You may wish to seek a solution to this problem, although the impact is usually negligible.

So following the error message instructions, I am seeking a solution to this problem. My automatic backups are also not running on this blog.

I have deactivated all of my other plugins except for Thank Me Later and I am still receiving the same error message.

I had the same problem with the WordPress 2.9 version on another blog, but I applied the Semiologic fix and that fixed the problem on that blog.

Does anybody know what I am doing wrong and how to maybe fix these problems?

Thanks so much!

WP-cron was broken in 2.9 but should work in 2.9.1 and later (btw there is already 2.9.2)

Try switching plugins in question off and on, re-saving their settings.

Thank you Rarst. I fixed the problem with my chron on the 2.9 version, I am looking for a fix with my chron on the 2.9.1 version. I also turned off all my plugins and turned them back on... Still no success. Anyone else care to take a guess at this?

Upgrade to 2.9.2 (good idea anyway), maybe update from 2.9 didn't go well.

Try dumping _get_cron_array() and see if default and plugin's events are there.

I am kinda new around these parts. What is the procedure for dumping _get_cron_array() and how can I see if default and plugins events are there?

[Rarst]

Add something like this in your theme footer, I added check for admin so it will only show to you logged in and not bother visitors.

 if (current_user_can('administrator'))
        echo '<pre>'.print_r(_get_cron_array(),true).'</pre>'; 
  

It should show array of all scheduled entries.

I use a plugin for messing with the cron system:
