+### File upload timeout
+
+File uploads in BookStack use a plugin called DropzoneJS. DropzoneJS is configured with a default upload timeout of 60 seconds. This means that if the file that you are uploading does not upload completely to the server within 60 seconds, the system will timeout. 
+
+To modify this timeout, in BookStack settings, Find the 'Custom HTML head content' setting and add the following code:
+
+```js
+window.dropZoneTimeout = 30000 // To se the timeout to 30 seconds
+```
