Drupal cron failed run to fix solution
- your cms version is drupal 7
- Backup and migrate modules has been disabled.
Run your cron. most of all will be fine.
If you can't run cron yet, you can check your php.ini follow this:
- make sure your setting: memory_limit = 128M or make it bigger (edit and change this in your php.ini file)
- max_execution_time = 300 or make it bigger
save it and upload your server, then restart your server.
The last way, we suggest to use Elysia Cron module to arange and allowing a fine grain control over each task and several ways to add custom cron jobs to your site.
