WordPress caught an error with one of your plugins, WP All Export.

Hello,

The WP All Export plugin crashed and I received these Error Details:

Error Details
=============
An error of type E_ERROR was caused in line 112 of the file /wp-content/plugins/wp-all-export/views/admin/export/template.php. Error message: Uncaught Error: Class 'XmlExportUser' not found in /wp-content/plugins/wp-all-export/views/admin/export/template.php:112

#5 /wp-includes/class-wp-hook.php(316): WP_Hook->apply_filters(NULL, Array)

I’m using WP_Query Results with the following configuration:
Post Type Query ‘post_type’ => ‘post’, ‘tag’ => ‘may-2021’

After clicking on Customize Export File the drag and drop area etc. are missing and I see only this text in a box:

WP All Export
Export to XML / CSV
Support | Documentation
Drag & drop data to include in the export file.

Please advise.

Thank you!
