Does not Play Nicely with SiteOrigin Pagebuilder

I don’t know where else to post this. But I want to use this plugin so badly! It’s just that every time I create something with SiteOrigin Pagebuilder, I get this:

empty string to a string offset in /home/______/staging/1/wp-content/plugins/ultimate-member/core/um-query.php on line 36

Also, it makes my pagebuilder fields extend well below where they’re supposed to. Everything works find when using one or the other, just not both at the same time.

I’ve been working on it in a staging area. I wish I could use both! I love both plugins, but wish they played nicely with each other! If anyone knows a fix, that would be great! Thanks!
