Hi Mark,
I’ve found an older version of the theme you are using on my test servers and I took a quick look. I’m not sure if you are using the same version, but I have found the problem.
Open up the wp-content\themes\wp_oswad_market\framework\functions\pagination.php file, and look for this line (line 86 on my screen):
[php]elseif(strpos($pageLink,’?’) >= 0 && strpos($pageLink,’&’) === false)[/php]
and change that to:
[php]elseif(strpos($pageLink,’?’) >= 0)[/php]
And that should solve the problem hopefully.
