Hello again,
It seems that the gallery upload (and login) is still rather screwy for some users. Since it's not affecting all users, it makes one think it is a client-side error rather than a server-side error (ie. a cookie problem, or somesuch). Consulting the Coppermine Photo Gallery FAQ:
I can't login to Coppermine. What's wrong?
This is most likely a cookie issue:
* If you're running Internet Explorer 6, you'll have to enable the acceptance of cookies. Click on "Tools" - "Internet Options" - "Privacy" and add your site to the list of sites that are trusted, or set the slider to a lower level.
* Sometimes IE will not handle Cookies properly. Close your browser, try deleting all local cookies manually and start your browser again.
* Check if you're running a software that interferes with acceptance of cookies like personal firewalls (ZoneAlarm, Tiny, Cookie Washer etc.) and turn them off to see if cookies are accepted then.
* Try using another browser (like Opera, which is rather small to download and can be removed easily). It's a generally a good idea to have some different browsers on your local machine to check if your site is displayed correctly not only in your favourite browser.
If none of this works, I'll continue my PHP-hacking to get the bugger working.
Once again, I sincerely apologise for the inconvenience, and I thank you for your patience.
Regards,
Aaron.
