You'll usually see the BLERK! ERROR 4 message when there's a problem loading your AOL Mail. Though this is often a temporary issue, there are a few steps you can take to get your back in to your mail quicker.
Restart your browser
Sometimes the old "turn it off and on again" solution actually works! Just close out whatever browser you use, then start it back up again. Once the browser has been restarted, go to to mail.aol.com and enter your username and password.
Adjust firewall settings
If your computer is protected by a firewall, this may prevent your mail from loading properly. From the firewall software on your computer or router, check the following:
* Disable any "web filtering" options
* Make sure it does expressly allow "http://*.aol.com"
* Make sure it does not expressly block "http://*.aol.com"
Clear cache, cookies, and history
Another option to fix the error messages would be to clear your browser's cache, cookies, and history. Doing this will wipe out all the little unwanted bits of info that have been stored in your browser, resetting it and making it overall run better.
Adjust Internet Explorer privacy settings
If you're using Internet Explorer, make sure the privacy setting is set to "Medium," or the default setting. Sometimes if the privacy setting is set to "High," it can prevent the mailbox from loading properly.
