Fatal Error - Need help

Hi,
Site was doing fine and then suddenly stopped working and giving this message on the homepage and all home page is blank except the menu bar
Fatal error: Cannot use object of type WP_Error as array in/home2/djtamuli/public_html/tamlee.com/wp-content/themes/blogspringtheme1/functions/dynamic-image.php on line 275

Removed all the plug-ins, but no change.
But, when I go to category page from the menu, I can see the usual layout.
Site: www.tamlee.com

Regards,
Dhruba

Update:
After some panic and a few litre of sweat, I remembered that it happened following a new post.
Removed the Featured image and it worked fine. The Featured image size was approx 2000x1200.
Do you have any size to any image upload?

Regards
Dhruba

 

Hello,

I think you are using GIF image due to which this error is occurred.
Use PNG format images for featured image and the recommended dimension for featured image is 670 x 335 pixels.

 

Thank you, Piyush
