WP PRO QUIZ – One of the Best Free WordPress Plugin for creating quizzes

Categories:

wp-pro-quiz By Julius Fischer is perhaps one of the best Free WordPress plugin for creating quizzes. There are many WordPress plugins out there for creating quiz website, but hardly any one of them is free. Free ones have features too basic and the advanced features required by you would be in PRO packages only. WP PRO QUIZ is simple yet powerful. It is not so fancy but it does the job well. It is completely free though packed with features and the quiz created using the plugin works well. However, the plugin was not under active development for a long time and the plugin is actually no more available on the WordPress plugin details page, where it says – “This plugin has been closed as of June 17, 2020 and is not available for download. Reason: Security Issue.” Last updated: 8 years ago as checked on 25/04/2023.

The WordPress Plugin is still used by a lot of websites as we can see from the recent comments coming in on the WordPress plugin detail’s page. If you have the plugin already installed on your WordPress website then it should still work. But there could be some issues if you upgrade PHP version etc.

WP PRO QUIZ Issues

WP PRO QUIZ plugin not found on WordPress

  • The plug-in is not available for download anymore. A message on the plugin page displays:
    This plugin has been closed as of June 17, 2020 and is not available for download.
  • If you have the plugin already installed on your wordpress website and it is being used, then you can still use it without any issues except PHP version which is discuss below.

WP PRO QUIZ unable to activate the plugin due to fatal error

error: Plugin could not be activated because it triggered a fatal error. Fatal error: Array and string offset access syntax with curly braces is no longer supported in /var/www/vhosts/AAAAAAAAAA.com/httpdocs/wp-content/plugins/wp-pro-quiz/lib/helper/WpProQuiz_Helper_Upgrade.php on line 69

  • If you have the WP PRO Quiz plugin installed before, but you deactivated the plugin to troubleshot some issues with WordPress, and then, if you try to reactivate WP PRO QUIZ plugin again, then you may get the above error which says:-error: Plugin could not be activated because it triggered a fatal error.
  • This is because of usage of deprecated curly braces in the code of WP PRO QUIZ which is not compatible with PHP version 8. Check which PHP version your website is running on. If the PHP version is 8 and above, lowering to 7.x version should fix the problem.
  • This can also be fixed easily by replacing the curly braces with ‘]’ as show below:
    • Open the file mentioned in the error message where the issue is, and replace the curly braces
    • From:  if ($version{0} == ‘2’) {
    • To:  if ($version[0] == ‘2’) {
    • Save the file
    • Try to activate the plugin again. It should work.

WP PRO QUIZ – Quiz is loading issue

  • In this case, when the user opens the page where the quiz is included, then the user gets the message “quiz is loading” but it never loads.
  • The issue is because of PHP version. WP Pro Quiz does not work on PHP version 8 and above. It works fine on PHP version upto 7.4.33.
  • If you upgrade the PHP version on your web hosting to PHP version 8 and above, then you will see “Quiz is loading…” error on your WordPress website.
  • If you are dependent on this plugin, the downgrade the PHP Version  to 7.44.33 and try again.

WP PRO QUIZ – page where quiz is included is shrinked one.

  • The issue is also because of PHP version. WP Pro Quiz does not work on PHP version 8 and above.
  • If you upgrade the PHP version on your web hosting to PHP version 8 and above, then you will see “Quiz is loading…” error on your WordPress website. And the webpage where the quiz is included is shrinked.
  • If you are dependent on this plugin, the downgrade the PHP Version  to 7.44.33 and try again.

These are some of the issues that I encountered with my WordPress website when I upgraded the PHP version to 8 without realizing that the WP PRO QUIZ plugin does not work on PHP version 8.  So I had to downgrade the PHP version to 7.44.33 as one of my website uses the plugin being a quiz website.

Do you have a quiz website on a WordPress? Which plugin do you use to generate the quizzes?  Let me know in the comments.
