Gallery doesn’t load until reloaded in editor

Hi,
thanks for your reply.

I load a (I thought it is called like this) block template, to have predefined Gutenberg blocks in a post. The part of SimpLy is this one:

		        [ 'pgcsimplygalleryblock/grid',
		            [
		                'copyRProtection' => false,
		                'sharePinterest' => false,
		                'sliderItemDownload' => false,
		                'shareCopyLink' => false,
		                'thumbClickAction' => 'useLightbox',
		                'collectionColumns' => 4,
		                'thumbSpacing' => 30,
		                'externalLink' => false,
		                'captions' => false,
		                'collectionThumbSubMenuDownload' => false,
		                'galleryType' => 'pgc_sgb_grid',
		                'align' => 'full',
						'className' => 'hit-gallery',
		            ],
		        ],

It loads an empty SimpLy-block in Gutenberg. I can fill it, but the problem is like described in first post.
I know that it isn’t the way a SimpLy-Block is used usual, but maybe there’s a chance.
As I said, when I reload the gallery before I publish the post, everything works fine. For me, it isn’t a big deal, but I try to make it for dummies, so my other publishers can’t create faults.

Maybe you have an idea. One way could be firing the “reload”-function, before saving the post.

Thank you!

Thank you.
Unfortunately adding images => [] to the block attributes doesn’t change anything.

I know it would be better to have the site online. I appreciate that you’re ready to help me. Tell me what you need to get a view into it and I will give it to you.

When I’m adding images to a new gallery in a new post, I can see in the Code, that everything is set correctly. Data-ID is set to every image. Data-link too. It seems to me, that one action isn’t fired, that normally is fired when inserting a new gallery-block by hand.
