HI @Marko Turic ,

 

Not sure if there's a bug in that version. After you attach the files, are you able to download it back with no issue? Is the preview only isolated to you? If so, you have want to try clear your cache.

 

If you are still running into issue, you may want to try the PDF Macro to see if its helps with the preview.

Yes it is only the Preview that doesnt work.
we have update our confluence 8.5.14 to 8.5.18 and had to do this two : The JDBC driver for MS SQL Server has been upgraded from version 7.4 to 12.6. If you are using SQL Server via JDBC and your database isn't configured for SSL connections, you must explicitly disable encryption in Confluence's connection URL string. With the updated driver, encryption is enabled by default. To disable it, append ;encrypt=false to the existing connection string. We recommend making this update before upgrading to avoid any downtime.

and fom them preview is not working 
tried everithing from cache clean to plughins reenable to restart confluence 
and nothing is working 

before update preveiw was working
