Hi,
I know there were many topics with “undefined” issue but I can not find solution for mine problem. I have hade some undefined issues before, but after upgrade to the newest version 8.5 i get undefined labels in table headings and after creating dropdown lists.
I had this happen earlier this week. The fix that worked was a Admin > Repair > Quick Rebuild, then going into the .htaccess at [root]/public/legacy and making sure RewriteBase was set to /public/legacy.
Did you able to fix it? If yes, post solution here.
no, it did not solve the issue…
