WP/LR sync, Real Media Library, Essential Grid problem

Hello,

I’m having an error that seems to be connected to WP/LR Sync, Real Media Library, and Essential Grid. I’m not sure where the problem might be coming from, so I’m checking with all the plugins.

When I select Real Media Library as a source for an Essential Grid gallery, the Please Wait message appears and the page freezes. I’ve made sure everything is updated and checked to see if there are any settings that need to be adjusted. I’m a novice at this, so there isn’t anything obvious to me.

Do you have any suggestions on what might be causing the problem and what might fix it?

Thanks!
Aaron
