Hello Adesh,
To fix this issue, kindly go to the file
/media/sellacious/js/field.uploader.js
find
var cInput or go to the line no. 80 and add
var fileName = fileObj.name;
fileName = fileName.replace(/[\/\\?%*:\s+|"<>]/g, '_');
and now find
.jff-uploader-filename or in line no. 85 replace
fileObj.name with
fileName
For clarification, take a look at below screenshot.
I hope this helps.
Thank You
