Why won’t my backup start?

There are a lot of external factors at play that can cause backups to not start. Many of them are due to wp-cron issues, some are caused by clashes with other plugins, others are due to non idiomatic WordPress configurations and a few due to software bugs. So, before posting to this forum please ensure you have answered these questions.

1. Does wp-cron work?
WPB2D relies on WordPress’ in build cron system, namely wp-cron. If this does not work then nor will your backups.

The easiest way to diagnose if this is working is to schedule a post a few minutes into the future and see if it posts. If it does not you will need to ensure its being allowed by apache by adding the following to your .htaccess file:

<Files "wp-cron.php">
Allow from All
Satisfy Any
</Files>

If that does not fix the problem and you are using a cache plugin, it could be that you are aggressively caching the file. If this is the case please ensure that ‘wp-cron.php’ file is in the cache plugin’s exclusion list.

Failing this you will need to contact your host and get them to help you diagnose why wp-cron and scheduled posts are not working.

2. Is it a clash with another plugin?
Once you are happy that wp-cron works the next step is to work out whether it’s a clash with another plugin. The best way to work this one out is to disable all other plugins and see if the backup starts, if it does then re-enable one plugin at a time until you find the culprit.

If you find a plugin that clashes with WPB2D, please let me know and I will endeavour to find the cause of the clash.

3. Do you have a non standard WordPress setup?
WPB2D is designed to work with a standard WordPress setup. If you have set up WordPress to run from a different folder or custom content folder then it will not work as expected.

If you fall into this category please feel free to post your custom configuration and I will see if it can be detected and backed up.

All of the above seems fine and I still have issues. What gives?
Unfortunately bugs are a part of software development and as much as I strive regression test my work. Sometimes issues can slip in. So if you have ruled out the above please feel free to post your problem with the following information:

1. Your WPB2D, PHP and WordPress version
2. A copy of the WPB2D backup log
3. Detailed steps taken to produce the issue
