There is error in your file. Replace all existing blocks and container with reference. Make sure you have parent theme configured correctly

[swleighton]

Removed most of the file to only leave the block that inserts a new item into the menu. The file is still failing to load

<referenceBlock name="catalog.topnav"> <block class="IBD\NavigationLink\Block\Links\Link" name="newpage" after="-"> <arguments> <argument name="label" xsi:type="string" translate="false">Contact Us</argument> <argument name="path" xsi:type="string" translate="false">contact</argument> <argument name="listcss" xsi:type="string">level0</argument> <argument name="css" xsi:type="string">new-test level-top</argument> </arguments> </block> </referenceBlock>

I fixed this by changing the "Type" field in the theme table for my theme back from 1 to 0.

And css/meu.css in httpdocs/app/design/frontend/Alothemes/digitalworld4/web/css/meu.css but not added on frontend.
No error reported also.
