Hello!,
I have a fresh installation and apparently everything is Ok until someone tries to access the chat, they get "You don't have permission to access /webim/client.php on this server." but can access by typing mydomain.com/webim/client.php I dont know what to do because I have already set the permission files in the /webim folder to 655 and also tried with 755.
I followed all the instruction you gave in the readme file you provided with the instalation pack.
PD: This problem does not appear on my localhost XAMPP instalation (Windows 7).
Thanks!.
