Only a link to the forum page is really useful – then we can see what is happening on the click.

Thanks for your quick response.  Here is the link to the forum:  http://coastalhomestead.com/forum

Well – that is a new one on me!

WordPress has a number of ‘filters’ that can parse the text being displayed primarily to make sure it is (a) displayable and (b) formatted correctly. This filtering takes place on the final page content before it is sent to your desktop from the browser.

Plugins (and themes for that matter) can create their own filters that can perform special tasks on the content. SP defines several – for displaying images for example.

I suspect (and it IS only suspicion) that you have a plugin active (although as I say – might be the theme) that is performing some sort of filtering that is having an effect on certain kinds of links. In particular changing the quotes used for the attributes in the html tag. Comparing yours to mine and everyone else –  there is a mismatched double/single quote being applied. This would normally only happen with a filter.

So – I see you have a lot going on there… any plugins that might be doing this?

I have gone through all plugins and individually deactivated them, tested to see if it affected SP, and then reactivated them.  Unfortunately, I didn’t see any difference. 

I really hope it’s not the theme doing this.

Unfortunately I only have a very basic understanding of html, so I’m a bit lost as to where to begin finding this mismatch you mentioned.  Is there any way of identifying this filter and disabling it without affecting SP or anything else on the site? 

The site isn’t being promoted yet, and nothing really is posted on the forum, so would deleting and reinstalling SP do anything positive? 

Thanks again for your help and hopefully this isn’t causing you too much of a headache

What is the theme? Is it a publicly available one?

Yes, it’s iMag Mag version 1.0.3 by ThemePacific.

I found the problem!  It was a plugin after all, a Google Analytics plugin.  Unfortunately it was a good plugin, but I’ll find a replacement.  Everything seems to be working fine again. 

Thanks a lot for all of your help!  This is such a great product you guys have.

Good find.
Er… can you tell me which one please. It is a great coincidence but I am actually in the process – this very moment – of installing a GA plugin in a site my wife runs so I don’t want to hit the same problem!
