Twentig, Essential Grid and large galleries

Hello,

After activating/deactivating my plugins one by one to find what could be causing a problem editing large 320+ image Gutenberg galleries that are restyled using the extension Essential Grid, I saw that there seems to be something related to Twentig. Essential Grid support has not yet replicated my issue and is suggesting that I search outside of their plugin. Hence this post.

The context: I’m a professional photographer, 56, trying to redesign my aging website from scratch using WordPress, FSE, Twentig, the Twenty-Twenty-Four theme and the fewest extensions possible.

The issue: Essential Grid has an add-on plugin/feature named ??Essential Grid WP Gallery Replace Addon?? which basically takes over site-wide the standard Gutenberg Gallery block layout and replaces it with a personalized grid configured with their main extension. I activated this feature to have a masonry layout on the photography galleries of my site.

The pain point is coming from the fact that some of my galleries hold year-long series of over 320+ 1600 pixel-wide images in a single gallery block. This has been working fine until now, but since I added Essential Grid to the game, these large galleries load okay on the front end, but choke when trying to edit them in the WP admin. In other words, they don’t load and result to a blank page.

Server and memory config issues have been investigated and I am quite confident that the issue is not there. If so, I would probably see other problems. In my tests, I have found that deactivating the Twentig plugin, let the pages load again in the WP admin. Not using the Essential Grid feature obviously too, but my whole point is to use it (and twentig too).

My WordPress setup and config is new, quite vanilla and my hosting service is quite generous with server resources. All versions are up to date and I tried different browsers (on Mac). I am obviously not a dev, but I have configured and managed WordPress sites since early versions. Also, I have not run into this issue when testing other gallery extensions like Modula or other.

My not-very-rational gut feeling is still leaning towards a problem on the EG side, but since their support person is in a ??not-us?? position, I am constrained to take some time to investigate elsewhere.

I would be happy to share configs, screenshots and screen movies in private messages, but for a few reasons, I do not wish to do this publicly here. Thank you for your bearing with me.

And thank you for any hints or clues that could help me investigate further and hopefully find a fix. I have a work around currently, which is deactivate plugins, edit my galleries and reactivate, but it is far from ideal!

Kind regards.
