@mewrd could be plugin or theme issues. Have you done basic troubleshooting like changing to Twenty Twelve theme and deactivating all plugins except BuddyPress?
the problem is that , well , i can’t see the problem ,i can login and logout from two different computers with no problems at all ,it is just that client that seems to have login issues . i don’t know how to fix a problem that i can’t see?
i have tried to switch themes and deactivate plugins .is it something in the htaccess file?
@mewrd
Try to get as many details from the client as you can. Browser, version and so on. Then perhaps try again using their exact environment. Might help you replicate the issue.
