The central temp folder is main->get_tmp_path(); ?>.
By default, this folder is created in the WordPress uploads folder (UPLOADS in wp-config.php.
Alternatively, you can control the specific folder for PDF invoices by using the
wpo_wcpdf_tmp_path filter. Make sure this folder is writable and that the
subfolders attachments, dompdf and fonts
are present (these will be created by the plugin if the central temp folder is writable).
If the temporary folders were not automatically created by the plugin, verify that all the font
files (from plugin_path() . "/vendor/dompdf/dompdf/lib/fonts/"; ?>)
are copied to the fonts folder.
Normally, this is fully automated, but if your server has strict security settings, this automated
copying may have been prohibited. In that case, you also need to make sure these folders get
synchronized on plugin updates!
