Hello,
Back in the office after the weekend.
I have just amended global-definitions as suggested ("true" in lowercase), saved the change and refreshed the site in my browser (I'm running locally on my Mac via the MAMP app). I've revisited one of the error pages and the error message (within the page itself) is:
Zenphoto encountered an error
Error: The album named cannot be found.
Backtrace:
-> Album->loadFileNames (class-album.php [349])
-> Album->getAlbums (class-album.php [375])
-> Album->getNumAlbums (template-functions.php [423])
-> getNumAlbums (template-functions.php [4286])
-> setThemeColumns (index.php [138])
I hope this helps. After my previous message I did retry making a Dynamic Album within the Default theme and it worked that time... so it seems a little bit random/hit & miss as to whether the error occurs.
Thanks again for your assistance
