Incorrect APP1 Exif Identifier Code

I have a blog post page, which includes a link to a template block to add additional images at the bottom of the post. If I upload a blog post image first, then add additional image function isn't available.

If I refresh the page without saving, the add an item option becomes available within the template block.

I'm getting the following error within php:

Warning:  exif_read_data(phpjDdCKU): Incorrect APP1 Exif Identifier Code in /Users/Grant/Dropbox/Sites/150-Dannenberg-Photography/public/perch/core/lib/PerchImage.class.php on line 536

Searching the forum resulted in this post. I followed Drew's advice regarding adding define('PERCH_ENABLE_EXIF', false);, however the issue still occurs.

Now a little stuck on what to try, the error is present on both localhost and live server.

Hello Grant,

I ran into the issue with image + blocks too. I think it's a separate issue from the EXIF warning you got.

What I found is if an edit form includes an image and some blocks:

<perch:content id="image" type="image" label="Main Image">

    <!--* Some Blocks *-->

When I add an image to the field image first then try to add any block I get some error in the browser console. So I normally add the image first, save and then start adding blocks.

Do you also get an error in the browser console?

Hi Hussein,

I do get a console error yes

That's the same error I get.

So would you class this as a bug, and there nothing I can do currently? Other than your suggested workaround?

Yes, it looks like a bug to me. I'd wait for Drew to have a look at this.

Great, thanks for the help, at least I know and can advise accordingly

Do you get the error with one specific image, or any image from any source?

Hi Drew,

Any image, any source

Is the same happening on dev and prod?

It’s is yes

Could you send us an example image?

Hi Drew,

Sorry for taking so long to provide this. Broadband issues.

In any case, these are just stock images that I have resized to file size. Nothing else has been edited.

If it helps, I see the same error in the browser console even when selecting an existing image from Perch Assets.
