5.3. Multisite - Changes only visible for admin and loggedin users

Hi,
i made some changes on one of my site inside the multi-site universe (16 domains). I can see the changes when im logged in as admin or user, but cannot view the changes on 'normal" browsers. I cleared, cleaned, deactivated everything whats close to caching (installation, server, browser) - so thats for sure not the point. I cleaned the database (with optimize), also no effect. It happens on all sites. Is there anybody out there who could help me out?
thanx in advance

 

Hallo,
alles gefixed: Es hat sich herausgestellt, dass das plugin wp-rocket installiert war und deinstalliert wurde. Die Cache-dateien blieben aber bestehen. Cache geleert über ftp - >wp-content > cache (Ordner bestehen lassen) und alles in Butter. danke.
