Hi,
Since a while some of the images that the users of my forum and I upload, and that originally shown great, with any troubles, it's been disappear. The images can't be accessed from the url (http://mypage.whatever.com/vbimagehosting/someimage.jpg), however they remains in the server (and can be download and perfectly seen from my FTP). When I see throught the Admin CP, it's shown the information, like in any other normal image (name, size, BB Code... those things), but not the image, only a blank space.
As I said, it's occurs with past well accessed and showed images, but also with some new uploaded images. (Some, not all of them). Also, if the new uploaded image not shown at firsts, it will not be shown on next uploads (for example, if I upload someimage.jpg and it's not showing, if I upload it again and again, the result will be the same).
And also, when I paste the url directly on my ?direction bar? (sorry, I'm not english spoken), it's redirects me to an vBulletin error page (something like "The specified forum isn't valid"). Since here, it's appear to asume that the root of my forum page is http://mypage.whatever.com/vbimagehosting/ instead of http://mypage.whatever.com/ (its means that if I click the banner to go to my index page, it takes me to http://mypage.whatever.com/vbimagehosting/index.php, that obviously doesn't exist).
I'm not sure, but is probably that it's only happen since I updated to vB 6.7; I'm using the script for months and not getting any trouble.
I hope someone can help me.
Thanks in advance. Cheers
