When going to "Enable IPv6" I am confronted with this message which I havent seen before.

Apache should be recompiled
Your Apache installation is compiled with v4-mapped support enabled. This is known to cause instability related to the way that Apache binds to specific ports. Please visit EasyApache and click "Build Profile Now" to recompile Apache with the proper options.
I have recompiled Apache but this doesnt disappear. Is it safe to ignore?

Hello :)

I believe this issue should have been addressed with internal case number 80697. Could you verify that you ran EasyApache and completed an Apache build successfully? Is it possible that your last compile failed?

Thank you.

To update, it looks like the patch for this issue will not be included until EasyApache build 3.22.22. To manually resolve this issue in the meantime, add the following line the /var/cpanel/easy/apache/rawopts/Apache2_2 file (or the file that's appropriate to the version of Apache installed):

Code:
--disable-v4-mapped
Then, run EasyApache again. Note that Raw Opts are documented at:

EasyApache - Raw Opts

Thank you.
