Hang on submit AND no results email sent after submit

[xandermaccyd]

Love this plugin but have just started to experience some very weird issues and can't see them reported anywhere else on here.

I can submit quizes (and successfully receive results) whenever I test using my desktop, laptop, tablet or phone. But 2 issues are repeatedly cropping up with lots of the people are who are trying to submit our quizzes...

a) Upon submit, the quiz page simply hangs indefinitely. No result is recorded on the DB. This is independent of device or browser and has happened with lots of people.

b) Upon submit, the result IS recorded by the DB (we can see the result inside the plugin)...but the user doesn't get sent their result email. This has happened to lots of people.

Would be very grateful for help with this, an understanding if this is a WP or plugin issue.

Some extra information for your Frank...

Re: bug 2, my developers seemed sure this was to do with Wordpress PHP email being erratic - so a plugin was installed to ensure that my Wordpress sends using SMTP. This didn't fix the problem...I got 4 people to take the quiz, two got their result instantly, while the other two were able to submit the quiz but no email was sent out to them.

Re: bug 1, the only thing I have been able to replicate is that turning off and on the setting that toggles admin email, seems to have an affect on whether a hang takes place.

I am almost certain this is not a plugin clash, or has anything to do with device or browser.

Hey @xandermaccyd

Thank you for choosing to use this plugin! I just went to both quizzes linked in the issue and submitted several times. You may want to delete my entries if you are doing any analysis on answers.

Hmmm... for bug 1, I wonder if it is the same issue from #505. I submitted 4 times but was not able to replicate this one. How often does this one occur? On one quiz (the pi-factor-quiz-ffp one), the results took a while to load the one time (about 10 seconds) but did load eventually.

For bug 2, this is something that has come up a lot over the years. Usually, using an SMTP system fixes this though. I took your quizzes multiple times with different email address to test different domains and clients but received the email all 4 times. How often does this bug occur?

I agree that we can rule out any device or browser issue.

Do you have access to a PHP error log to see if there is anything in there? Would it be possible to temporarily turn on WP Debug mode, submit the quizzes a few times until you encounter one of the bugs, turn off WP Debug mode, and then copy contents of the debug log here?

Hey Frank, Big thanks you for getting back to us. Afraid we have run out of time - our quizes are a big part of our marketing and we've got to get going, so we've had to go with a different option: this is a shame as we are real fans of your plugin. Re: bug one - it's tricky, as I cannot replicate...however, lots of people have sent me screenshots showing the quiz hanging. I am NOT a techie, but I do wonder if it has something to do with tags and bits of html creeping onto pages and confusing the system. I only say this because my quizes ran smoothly until I started doing lots of rewriting, cutting and pasting into the results page etc. I wonder if there is something on the results page (but not visible in the text editor) that causes the end of the quiz to stall. Of course, if that is when the email is triggered (prior to the results page appearing), it could also be related to bug 2. Incidentally, one one occasion, when someone was experience the hanging problem...I was temporarily able to fix it...by turning admin emails off: but after this allowed one person to re-take the quiz and get past the hang...for another person, for whom the quiz had been working, this caused the hang to occur. As for bug two...this happens about 50% of time...although I can't detect any rhyme or reason to it. I really doubt this will be of any help, but here is a screen grab (see attached) of three fails from my SMTP service...like I said, I'm not a techie at all, but it's interesting that all 3 messages seem to be about different things. We are super busy, but if we eventually have time we'll try and check the PHP error log + run WP Debug Mode - however, I think we'll have to leave it for now. All the best and thanks once again for coming back to us, Alex McDonald & Jodi Goldman

Hi,
I have encountered same problem. I found out it was due to wrong email message template content. I have put variables in wrong format, precisely, it was typo in %CATEGORY_POINTS%%/CATEGORY_POINTS%. So check your email templates and also result page template.
