Advanced_URLFilter does sometimes not apply rules anymore

[Crashdummyy]

Router Model Affected DSL-AX82U

Firmware Version Affected 388.6.0

Is this bug present in upstream Merlin releases too? Actually no idea. It worked fine until the update yesterday ( previously on 388.2.0

Describe the bug Updating the list does not alter the content anymore. When I clear the whole list it appears I'm able to introduce new entries again. It has to be something internally because the request looks okayish I guess. ( whats that + doing here? +mediaservices.cdn-apple.com )

The issue appears the moment I try to insert eg "service.idsync.analytics.yahoo.com"

current_page=Advanced_URLFilter_Content.asp & 
next_page=Advanced_URLFilter_Content.asp &

Tested on my DSL-AX82U with 3004.388.6_2-gnuton0_alpha1 and I cannot reproduce it. it works for me. Maybe you have edited your settings and you broke them. Try to reset it

It's as I wrote. I did reset everything and I am able to configure the list again.

However when I insert service.idsync.analytics.yahoo.com to the list it doesnt get updated anymore. In my case I could successfully insert it on 388.2 leaving the list unchangeable once I upgraded to 388.6.

I don't see any form of validationerror it just doesnt update the list when I try to insert an invalid address

[gnuton]

there is validation for inserted strings. You cannot enter anymore more than 31 chars.

Okay I am apparently hitting this limit. I think it'd nice to get some visual feedback and not just this entry not being inserted into that list.
