Dear Comunity, I would like to report the following BUG tested on the current egroupware.net Testsystem. When you upload a file to an EGw app, then in most cases the thumbnail is not shown in the filemanager. For example if you upload an png file to an infolog entry and the thumbnail is shown correctly in the links tab: But if you head to /apps/InfoLog/5 in filemanager you can see the file, but the thumbnail is not loaded: The thumbnail of the file is shown correctly if uploaded to the home directory i.e. /home/sysop/test I discovered that the problem happens when the system tries to load the image via thumbnail.php https://XXXXXXXXXXXXXX.egroupware.net/egw/api/thumbnail.php?path=%2Fapps%2FInfoLog%2F5%2Fhelp.png&thsize=64&mtime=2021-03-06T10%3A31%3A16Z" Thank you and best regards, Alex
