Hi,
I see that there are a few topics open related to this issue, however, I can’t see any solution to my problem. I have just done a long overdue update to my site. The update included the latest WordPress and the major Woocommerce updates. I have not updated download Manager on the live site but have on the staging site.. Both sites have the same issue regarding corrupted files.
The plugins (all updated) used in this website are:
Akismet
BackWPup
Contact Form 7
Contact Form 7 Pro Lead Capture
Download Manager
Force Regenerate Thumbnails
Post Duplicator
Post Types Order
Revolution Slider
Taxonomies Filter Widget
WooCommerce
WooCommerce – Store Exporter
WooCommerce Predictive Search PRO
WordPress Importer
WordPress SEO
WP All Import
WP All Import – WooCommerce Add-On
WPBakery Visual Composer
WP Multibyte Patch
X – Shortcodes
Thanks
