What version of PHP are you using?
That version is not even supported by WP anymore – https://ww.wp.xz.cn/about/requirements/
You will need to update PHP to get support for some of the newer features.
We simply use an anonymous function described on the WP Codex to grab all usermeta and trim out empty array values – http://codex.ww.wp.xz.cn/Function_Reference/get_user_meta#Getting_all_meta_data
Sorry, it’s version 5.2.17 and this is the only plugin that shows that error.
5.2.17 is still not a supported version of PHP.
Each plugin is written differently and uses different functions – we can see the issue and will look into alternatives, but there is not set date for when we’ll release the next update.
Q
I asked my hosting to update the version of PHP to 5.4 and now the plugin is installed, but couldn’t get to export the file, is there a limit of users? In my case I have 16,500 users.
Good progress.
The export has an option to limit the number of users your export – perhaps 16,500 is going to kill your available memory – look at the “advanced options” and batch the exports.
Thank you for the fast response! Got it solved by making batches of 5000 users.
Good news – don’t forget to leave a review 🙂
Q
For any users on PHP < 5.2 – we’re working on a fix that removes the anonymous functions – it can be tested from github: https://github.com/qstudio/export-user-data
