Avast Free! Site Blocking in Web Shield won't work

This happens instantly when program updated to the newest version 18.5.23.42.
Every time I check “Enable Site Blocking” and click OK, soon it greys out automatically.

Same here.

Same here and for an other french user.

Hello,

At time Site blocking doesn’t work anymore

Reported to developers.

Hello,
is it really so hard to fix ?
soon 2 months that version 18.5.2342 is out (and issue with)

Updated to 18.6.2349 - No improvement: Still not fixed on 21 Sept 2018.
Maybe Avast doesn’t consider these features as essential and like to spend more effort on pushing the sales of their additional bloatware-like packages? Already managed to get out of Auto-renew…

Works fine for me since 18.6.2349…Maybe something wrong on your part?..Did you tried a repair ?

18.6.2349

Fixed:
  • Firewall notification not displayed when network changed
  • Detection dialog not displayed for Web Shield when set to Ask
  • Wrong reporting of Wi-Fi Inspector scan progress percent
    - Site blocking works again
  • Rescue disc
  • Reporting of AV and Firewall state to Windows Security Center
  • Explorer scan result not added to Notification Center
  • Removed Enable offline mode option in free version tray icon

Repair Avast:
