Please explain: Difference in blocking IPv4 and IPv6?

Can't use LTD (lighttpd issue). Can use Query Log - Show all

apt-get update on the client gives expected results.

msn.com in browser gives one query (A) OK. I whitelisted msn.com. Next domain in chain is blocked.
When I remove msn.com from the whitelist it is Blocked (gravity, CNAME)

Mine are. Don't know about @jpgpi250.
Can I go back to release/v5.0?
Will the patch be merged before release? I know I will loose the patch in the meantime.

Yes, this will all go in to the release. I don't know if the branches are compatible yet for going back to beta5.0 branch but if you give us a few hours to review and merge that branch in then you should be able to return to beta5.0 branch. Once Improvements to deep CNAME inspection data processing by DL6ER · Pull Request #685 · pi-hole/FTL · GitHub shows a purple Merged flair then you should be good to go.

Thanks, I will see when it's merged.
Now going back to release/v5.0 to rule out if this patch is the cause of a Fatal PHP error in Long term data.

There is no PHP error release/v5.0.
Is it correct to apply your patch by checking out core/web/ftl of your patch?

Please open a new topic for any PHP errors. This topic/thread is resolved.

List any steps you have taken and what errors you are seeing.

Sure but I think your patch for this topic is the cause of the PHP error.

Thanks, 94 posts in a topic is too many. We need to keep things on topic and short to review.

Can't reproduce PHP error. Forget about it. Thanks for your help in this topic.

Check.

Just updated - looking and working fine so far. One small thing happened, don't know if it had something to do with ne new code:

The lighttpd error log was flooded extremely with

unexpected "=" in pihole-FTL.conf line 4

and a relating PHP error. The reason for this was that the pihole-FTL.conf must be rewritten during the update process and looked like this:

BLOCKINGMODE=NULL
MAXDBDAYS=30
RESOLVE_IPV6=yes
RESOLVE_IPV4=yesPRIVACYLEVEL=0

The web interface did its work anyway. I added the missing linefeed, stopped lighttpd, deleted its large error log, restartet it and no error occured so far.
