Same problem here. I think it’s because of the translation. In Dutch the tab is now called “Resultaten pagina’s” leading to the link “tab=resultaten-pagina%27s”. That apostrophe is likely the culprit.
Update: confirmed that this is indeed the problem. I removed the apostrophe from the translation and now the results tab is back. Yay!
Now it’s up to the plugin developer to change the translation or, even better, find a workaround so apostrophes in translations don’t break functionality.
Meanwhile, you can fix your website by downloading POedit (free, open source), download and open “\wp-content\languages\plugins\quiz-master-next-nl_NL.po” from your website, search & replace “pagina’s” with “paginas” and upload the back back to the webserver.
Hey @veertje1992 and @inflection,
Great catch Ron van der Kolk! There definitely appears to be a bug in the plugin that prevents apostrophe’s from being in the translation for the tab text. Let me get an update out to fix that!
Thanks for reporting this bug!
Hey @veertje1992 and @inflection,
Can you upgrade to the latest version (4.7.8) and let me know if you are still experiencing this issue?
Sorry for my late response, had some issues over here (not related to the plugin).
I’ve tested it and it’s working 🙂 Thanks a lot!
