Hello, 
I am experiencing an issue with the Materialize theme and WPbakery Page Builder. When the Page Builder plugin is activated, any new uploads to the media gallery are put into a folder for September 2011. When I deactivate Page Builder, new uploads go into the current date folder as expected. Existing photos in the media library that were uploaded this month have also randomly changed paths to the 2011 folder, which is causing large batches of images to go missing at random times. When the theme is deactivated, but Page Builder is left on, the issue is also resolved. I have submitted a support ticket with WP Bakey and they are claiming this is a theme issue. Any assistance with this matter would be greatly appreciated!
