log out error

Dolphin 7.1.6 has no logout option both for admin and for members.

When clicking on logout page disappears and blank page opens. Logut doesn't complete.

http://1circle.org  you can create test account and examine.

Can anyone help ?

A blank page usually means a PHP error. Check the error_log for any entries with a timestamp that matches, or temporarily turn on display_errors in the php.ini file:

display_errors = On

Then try and reproduce the issue, and post any error messages here.

try to manually upload the logout.php file again from the install zip

display_errors = On

 Unable to find php.ini file

In which folder this file exist ?

You can try creating it by placing the file in your /public_html directory with those contents. Otherwise look for an error_log file, which will also track any error messages.

 There is no logout error in error_log file.

You need to look for an entry in the file with a timestamp that matches. I do see a lot of 'out of memory' errors. What's the value of memory_limit? Check under Admin Panel => Tools => Host Tools => phpinfo. Dolphin needs it to be at least 128M to work properly.
