CiviCRM 4.6.8

I was editing an email when the "Send test" button triggered the message...

Error: Sorry an error occurred and your information was not saved

Unable to replicate in demo site since there's no outgoing email (saving the email doesn't actually produce the error, despite the error's wording).

I went in and submitted a test mailing that I wasn't able to preview. This caused the cronjob to spit out the error: 

<br />
<b>Fatal error</b>:  Call to undefined function mb_strtoupper() in <b>/home/ourbase/public_html/sites/all/modules/civicrm/packages/html2text/rcube_html2text.php</b> on line <b>703</b><br />

The key there is the function mb_strtoupper() [that's "string to upper"]. To fix this, you need to enable "mbstring" on your php/apache build. In my case, this was done through the WHM interface as follows:

  1. Go to EasyApache
  2. Customize the current profile
  3. On Step 3 (?) click on "Exhaustive Options"
  4. Check the checkbox for MBString
  5. Build & Compile (takes a while), and wait until it's done.

If you don't have access to that solution, consider one of these lesser temporary solutions while you wait for someone to resolve it: 1. Remove all <strong> and/or <b> tags or... 2. Manually put text in the plain text box

I received this message because my Firewall (CSF) was improperly configured to block the outgoing mail port. When I resolved that, the error disappeared.
