Not possible to disable CAPTCHA for Public user group in Settings > Permissions > Public (JComments 3.0.0). After saving the changes "Enable CAPTCHA" check-box gets checked again.
The issue is a bug confirmed by JComments developer "smart" here.
A small office reported an issue with their Internet connection - some websites wouldn't load at all, some load incompletely, and others work absolutely fine. The office had a SonicWALL NSA220 firewall connecting to the Internet via BT OpenReach VDLS modem (over PPPoE). Standard network / Internet connectivity tests didn't show any problems.
I have a few websites that run Joomla and send some notification emails via Godaddy SMTP server smtpout.europe.secureserver.net. Godaddy only allows 250 SMTP relays per day for free, but for this particular purpose this was more than enough.
One day I noticed that I was not receiving all notification emails I was supposed to receive. First of all all I logged on to Joomla's administration panel and tried to send some test emails using Joomla's built-in Mass Mail functionality. Results were interesting - most of the time emails would go through, but around 30% of the time sending would fail with error:
The following from address failed: This email address is being protected from spambots. You need JavaScript enabled to view it.
Noticed that few of my Joomla websites were still on version 2.5.11 when the current version was 2.5.19. Joomla auto-update page was misleadingly saying that Joomla was up-to-date.
