Dear sir.
I do all of this but my roundcube webmail continue with error 500.
log :
[Tue Feb 19 12:07:50.761225 2019] [fcgid:warn] [pid 23206:tid 140419207698176] (104)Connection reset by peer: [client xxx.xxx.xxx.xxx:35742] mod_fcgid: error reading data from FastCGI server
[Tue Feb 19 12:07:50.761272 2019] [core:error] [pid 23206:tid 140419207698176] [client xxx.xxx.xxx.xxx:35742] End of script output before headers: index.php
Can you help me ?
Hello @Apsides Communication,
Alternatively, it might be caused by insufficient permissions for the /etc/passwd. Permissions should be set as in the example below:
# ls -la /etc/passwd
-rw-r--r-- 1 root root 3100 Feb 5 14:58 /etc/passwd
If permissions differ, change it with the following command:
# chmod 644 /etc/passwd
If the error remains, contact support for the help: How to submit a request to Plesk support?
Thanks for reply but issue is same.
thanks it worked for me!
