When an email goes through to a user notifying them of a new post that they have subscribed to, or they are receiving it as a moderator, it contains a link to the post.

This link looks something like this: URL : www.clubmotorhome.co.uk/forum/5-motorhom...s-for-2016/7124.html

Sometimes when clicked this results in an Error 500 display. Refreshing the page always corrects this.



This happens on any device and browser.

When the link clicks through properly the URL displayed has a different ending - www.clubmotorhome.co.uk/forum/5-motorhom...6.html?start=24#7124

Any ideas what is causing this please?

could you enable kunena debug. And check again. You get now the real error message

Thanks for your prompt reply.

Have just tried with debug on but unable to get it to do it again - the problem with an intermittent fault

Is there anything else I can check?

wait for a new notification, if you don't get the error, then its looks its fixed.

OK, just tried again and got this

try with the default kunena template. then do the same thing again.

OK, same result - line 33 in application.php
