Hi Keith, Take a look at the hints/tips in our Installation Docs for "No _links section found at.." errors: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-%22No_linkssectionfoundat...%22errorfromUserInterface
It sounds like your UI cannot "see" your REST API at https://utley.lib.udel.edu/server/api (or it's somehow being blocked?)

I am able to run the front end using the yarn start. When I go to the url, I get some interface response but I'm also getting the following errors: Environment: Production No _links section found at https://utley.lib.udel.edu/server/api No _links section found at https://utley.lib.udel.edu/server/api No _links section found at https://utley.lib.udel.edu/server/api and errors continue: ERROR Error: undefined doesn't contain the link sites at MapSubscriber.project (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/dist/server/main.js:256927:23) at MapSubscriber._next (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/node_modules/rxjs/internal/operators/map.js:49:35) at MapSubscriber.Subscriber.next (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/node_modules/rxjs/internal/Subscriber.js:66:18) at MapSubscriber._next (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/node_modules/rxjs/internal/operators/map.js:55:26) at MapSubscriber.Subscriber.next (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/node_modules/rxjs/internal/Subscriber.js:66:18) at TakeSubscriber._next (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/node_modules/rxjs/internal/operators/take.js:54:30) at TakeSubscriber.Subscriber.next (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/node_modules/rxjs/internal/Subscriber.js:66:18) at FilterSubscriber._next (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/node_modules/rxjs/internal/operators/filter.js:52:30) at FilterSubscriber.Subscriber.next (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/node_modules/rxjs/internal/Subscriber.js:66:18) at MapSubscriber._next (/home/dspace/SOFTWARE/dspace-angular-dspace-7.0/node_modules/rxjs/internal/operators/map.js:55:26) Then I am getting some 200 reponses: GET / 200 506.147 ms - - GET /styles.0324863878df4752a58c.css 200 4.651 ms - 346 GET /dspace-theme.css 200 1.231 ms - - GET /runtime-es2015.bfc7b4c3632b68fcfa67.js 200 7.956 ms - - GET /assets/images/dspace-logo.svg 200 8.637 ms - - GET /polyfills-es2015.473cd1992a6ad138d0e6.js 200 3.538 ms - - GET /main-es2015.1404cdbe3f3368ec46fa.js 200 5.493 ms - - GET /assets/fonts/fa-solid-900.woff2 200 1.171 ms - 80300 GET /25-es2015.b09d3ba9b53c98168491.js 200 8.464 ms - - GET /assets/i18n/en.json5 200 6.916 ms - 126854 GET /79-es2015.1d3d2d87bd7969ff080d.js 200 3.644 ms - - GET /80-es2015.1628eec9b3c265b32bc3.js 200 1.180 ms - - GET /82-es2015.9124c792844bf9d9a09c.js 200 2.031 ms - - GET /common-es2015.a61f806adcb8ed987a9a.js 200 7.944 ms - - GET /assets/images/favicon.ico 200 1.089 ms - - Still when I try to compile and run the front end, i'm still getting the same error.
