When a user tries to upload an image I see following message in firebug:
TypeError: this.uploader.settings.filters[0] is undefined file_extn = this.uploader.settings.filters[0].extensions; rtMedia…bone.js (line 349, row 7)
rtMedia v4.0.4 / BuddyPress v2.6.1.1 / WordPress 5.5.3
Any idea what may cause this?
Best regards, Jan
