PDF & ZIP thumbnails not visible for members April 08, 2020, 12:30:19 am A member just reported that the thumbnails of zip & pdf attachments are not visible. Global moderators and admin member can view correctly the thumbnails of zip and pdf attachments. I do allow members to post and view the attachments without approbation. Guests can also view attachments, but those thumbnails are not visible for guests. As a member if I try to view in browser the thumbnail image (index.php?action=dlattach;topic=5310.0;attach=6472;thumb) I get an error: You do not have permission to approve items.I cannot reproduce this on elkarte.net. Any idea on how to solve this?
