I am unable to run cron on a Drupal 6.25 web site.
Running cron using both the run cron option from administration menu and the run cron manually link from status report page results in the following message:
The warning message next to the cron maintenance tasks entry on the status report persists and cron hasn't run.
I recently upgraded to latest version of Drupal. This issue also affects development copy of web site.
As always, I ran update.php after upgrade - no errors reported.
Tried changing number of items at /admin/settings/search to 10.
Can anyone advise how to fix the problem?
