title: Magento not rebuilding product image cache
body: <p>After clearing Magento's image cache, the site seems unable to rebuild image caches and certain pages are loading with a url extension ?___SID=U. All product images are coming up blank and look to be halting further loading of the site (no footer or sidebar loading on those pages).</p>
  
  <p>It seems to be a permissions issue? Relevant folder (media) is currently recursively set to 777. But I'm still having issues.</p>
  
  <p>Also renamed the htaccess in media to htaccess-old</p>
  
  <p>No luck. Can't upload new images either. And no the server isn't out of storage.</p>
