Hello @balramverma
Hope you’re doing well!
I apologize for the delayed reply.
It seems that this is related to your site setup because I can’t replicate the same from my end.
In order to find a solution we need to identify the source of that conflict with Hustle, so please run a full theme/plugin conflict on your site.
– Deactivate all plugins, except Hustle
– Switch to a Default WordPress theme
Check if the changes can be saved. If all is well, activate one plugin at a time, each time, saving changes in a plugin, till you replicate this issue.
Also as @sertys mentioned in the above post, would you please make sure that the tables are set correctly in DataBase tables?
Let us know how it went!
Kind regards,
Nastia
