Hi there,

By default .png files should not be filtered. Does it happen to all .png files or just a specific one that you are trying to upload?

Besides, that you could edit your wp-config.php and add the following line:


Best place to add this is right above the /* That’s all, stop editing! Happy blogging. */ line.

Let me know how it goes. Regards, Bobby
