Moodle 2.5/2.6 must have been the time that feature was implemented. I thought the yellow warning still appears when the network connection breaks during a test. Does you client have a problem with JavaScript. Switch on JavaScript debugger and "pull the plug" during a test. ;)

Moodle in English -> General help -> outgoing mail server -> Re: outgoing mail server

General idea of sending mails out is documented here Mail_configuration#Outgoing_mail_configuration. One screenshot shows that you are trying office365.com. It needs specific instructions. For example there is a Email_setup_gmail page, which refers to this discussion https://moodle.org/mod/forum/discuss.php?d=455703#p1830642.

*Sending* mail is not Moodle's job. It prepares the mails. To *send* Moodle needs the help of an SMTP service.

That said, there is an error pointing to open_basedir() . Can you deactivate it and try?

"Dedicated server 8 gig ram, 4 dedicated cpu" is still a virtual machine, I believe, as in https://en.wikipedia.org/wiki/Dedicated_hosting_service. Nevertheless a 4 cVPU, 8 GB RAM server should not struggle.

What is the Linux distribution and its version? PHP is 4.2 you said. What is the DBMS and its version? The web server: Apache? Litespeed? Nginx?
 
No Redis in 4.3? No Redis in 4.5 LTS?

It was running smoothly with Moodle 4.3?

Side question, which is not going to help you: Moodle 4.5 LTS is just a week old. Why the rush? Did you rehearse on a staging server? Likely not.

So you upgraded exactly as documented in Upgrading? You had the habit of overwriting code: https://moodle.org/mod/forum/discuss.php?d=461580#p1853324.

Site administration > Server > Environment all green?

Site administration > Server > Session handling?

Site administration > Reports > Performance overview all green?

Did you go through similar hints in the Performance documentation and read the Performance FAQ?
 
And there has been a recent collision with Microsoft: https://moodle.org/mod/forum/discuss.php?d=461580#p1853324. Has it been resolved? How?

Hi Astor

It would have been really elegant. We are running a "slow" workshop where the participants convert a collection of basic programming exercises to VPL, VPL questions and CodeRunner - soon on auto-pilot. (You must have got the announcement. It is on the same site where you introduced VPL to our people. I see that your account is still active, appreciate you being there.)

The participants are from different institutions and speak different (computer) languages. At the end of the workshop they take the collected creations home. There is a big difference in the number of activities and quiz questions they create whether there is one per language or one for all four languages. If there's a solution by end of January, we can still incorporate it before end of March, when the workshop ends.
