My forum Use Image Lightbox with option to Click on attached image thumbnails and I don't see the image,is not load the image.. error...why?

You should try rebuild attachment thumbnails under

Maintence --> Update Counters --> Rebuild attachment thumbnails

Maintence --> Update Counters --> Rebuild attachment thumbnails don't work
If I do not Use Image Lightbox when I Click on attached image thumbnails it' work ok.....but I want to Use Image Lightbox.

I have resolv the problem
In the folder that I create for Attachments to the Filesystem in the public_html with chmod 777 I put a file .htaccess with 777 permission...and now I delete this file and Use Image Lightbox is work very well.
Thanx and close the thread.
