HI, after having accidentally updated all custom Lovelace cards on my HA 84.3 system, which was no good idea because of incompatibility issues, I am reverting to a backup of cards. Most of them work fine again, but the fold-entity-row keeps giving me this:
## Log Details (ERROR)
Mon May 06 2019 11:36:57 GMT+0200 (CEST)
:0:0 SyntaxError: Can't create duplicate variable: 'LitElement'
and the red card:
of course I have renumbered the resource in ui-lovelace.yaml and refreshed, emptied et etc, restarted even.
Since card-tools is needed for this card, I have also reverted that card to the previously working version.
still no such luck.
Please what would come to mind to get this back up and running again?
thanks for having a look
