Hey @jwjena ,
We found that the [Not a valid template] issue occurs either when using a custom template for you gallery layout or if you had a Legacy (Old) Template selected on a gallery.
Our team is aware of the issue and is actively working on a fix that will be included in an upcoming update.
In the meantime, if you were not using a custom template for a gallery, then you could you please be sure none of your galleries are using a Legacy Template?
To do this go to a page with a gallery using the NextGEN Gallery Legacy block > Edit gallery > Customize Display Settings > make sure the Legacy Template is set to Default: https://a.supportally.com/i/P2Hh1c
I’ve marked this thread to reach out as soon as the update including the official fix for this has been released!
Thanks!
Hey @jwjena
I wanted to let you know that we just released an update for Imagely that includes a fix for the [Not a valid template] error.
Please be sure to update your NextGEN Gallery plugin to version 4.0.3 to start seeing this addition.
I hope this helps!
Thanks! 🙂
