I suppose this conflit it is coming from Helix Ultimate 2.0.12, but, knowing that soon you are releasing some fixings here, would be useful to exclude the JFBConnect as possible cause.
The Bug is described in this GitHub report: github.com/JoomShaper/helix-ultimate/issues/317
And I have back it also on SCLogin module (you can find it in the left Off canvas position).
Sure I have:
- JFBConnetc > Configuration > Advanced > Load jQuery/Bootstrap: No
- JFBConnetc > Configuration > Advanced > Load Bootstrap CSS: No
Waiting for your reply, Friendly Regards
