The same problem happened with me.

$ cat /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=permissive
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

Can anyone give me any suggestions for fixing this problem?

How to disable Instant Messenger Plugin?

Thanks,
Regards

SELinux is disabled on this server

Do you have SELinux enabled on this server?

seems to be an issue with the Instant Messenger plugin.

If I disable the plugin the "My Account" page works without problems.

some extra information - The server is running Centos 6.7 not 6.6 as I mentioned in the summary.
