Well I know 2 users who cant login and they are using Chrome as their browser. But the girl with the account I gave made a new account with chrome which worked. I did register again and I got an error message, but still able to login/out. Here's a pic:

Well looks to me that your site has the same problem as Aasix's. Read this post and edit a line in functions.php will get rid of these warning messages for you. Not sure if this helps with 403 forbidden error though:

oo thanks that did fix the error messages but not the 403 login bug. T_T Someone who could login a few days ago can't login now as well.

Ok I totally reinstalled everything and created a new database. Want to try to test an account? I made some and it seems to work but I'll ask some other people.

edit// nope still same 403 xD People say they get this message at the bottom too " Apache Server at adragonsden.com Port 80 "

2/3 members can't login but the 1 can (other than me) xD

Just registered for an account and I'm not having any problems with logging out and back in.

Strange. It just seems like hit or miss with logging in. I finished doing all my adoptables (after weeeeeks of work) I'll continue to build it and see if members can just make new accounts if they can't log back in.

btw; is there a way to make the user login non case sensitive?

Well yeah, its difficult to troubleshoot a problem like this, both Nyxi and I do not get login problem after registering on your site. Are there any similarities among the users who cannot log in? I mean, similarities other than the fact that they cannot log in?

umm you want to make Username non-case sensitive?

I cant seem to find similarities with the users who can't login. :c

And yah, if it's possible for usernames to be non-case sensitive,it might be more convenient with having a login issue o.o

Well do some of your users have symbols and weird characters in their username? This may explain why it is not working out for them? And to make username case insensitive, just add strtolower() to the register.php page on username variable. It should be simple.

thanks for the help with the non-case sensative username :D

and nope the usernames where simple. The ones who couldnt log back where Nocturnal and Doimatest2. the doima guy has made several accounts and cant seem to get it working at all. I had another friend try and her first account got the error then her second account worked. so strange :c

"You don't have permission to access /adoptables/login.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.". maybe its just my host ><
