Made few changes to the bigpicture theme and now the homepage is not displaying. I am able to see the item pages and the collections pages but not the homepage. I checked the error log and get the following error codes:

Could someone help me?

There may be an issue in the original theme. In fact, as in https://github.com/omeka/theme-bigpicture/blob/master/collections/featured.php#L1, the featured collection should have a representative image, and if not, an error occurs. If this is not the issue, add a check to see if there is an image on this line 1.
