The file is: public_html\ledigehjerter\wp-content\plugins\blog-manager-light\assets\js\otw-admin-bm-functions.js
and I have added an extra line, number 5.
The search back-end works now, but it's not a long term solution, since upgrading this plugin will overwrite this change.
If the issue appears again, just disable the Blog Manager Light until you configure the search, that's probably the best way to deal with the problem 🙂Best,
