I'm having a major issue and I'm not sure how to resolve it.
I have a WordPress multisite network with the first site in the network: netmix.co
Additional sites are:
All my content is there, but all theme images and CSS and thumbnails on the site and in my admin are now unavailable. I'm thinking this is a server/permissions issue and I just can't figure out how to solve it.
I have an .htaccess file in the wp-content folder, but I disabled it and that didn't help.
I turned off all plugins and swapped a theme like Twenty-Twelve, and all theme images were still broken.
I do have plugins like WP Security Scan and Sucuri and tried to harden WordPress and I think this is when this started to happen. The only way to bring everything back is to go to an older backup and restore.
Checked all folder permissions for wp-content, themes and theme folders and they are 755.
Any words of advice?
