Why is it that when using Safari 5.1.3, I have to re-enter my login details whenever replying or posting on 7.5.x? It is something I can fix on my own laptop, or is it a global issue? BTW, it does not occur on this UBB site, but on sites that use an .htaccess file for login.

I have never used safari myself.
But my iphone buddies tell me that is what is on the iphone and they do have issues with some file attachments.
So it may just be another buglet with UBB such as the new versions of IE.

It could be a bad cookie. Try deleting all cookies involved with the sites your having issues with.

As far as I can tell, it's an issue with the CC Bill integration with UBBThreads and the .htaccess file handling, as the 2 sites I have this problem with, both have that mod. I hope any new release will have IOS uploading attachment features. I would love to update and report when out and about...
