Hi Keenthemes,
After upgrading from 8.0.34 to 8.0.36, the invalid message for input group are not showing,
I may know the reason, it"s when you updated the text color inside input-group lately changed. (wich is looking goood), but it maybe this update on input-group affected the css reposnsible for the invalid section.
here the invalid validation input-group :
this is 8.0.34 : https://ibb.co/gr8xpnC
this is 8.0.36 (The bad render): https://ibb.co/r609JXb
NB : Just to let you know that in either version the Div class="fv-plugins-message-container invalid invalid-feedback"
is showing normaly just in the 8.0.36, no visible red text showing.
thank you.
