SCLogin not working on all pages - #login-modal

There's quite a few possible causes for that error:
* page caching,
* 'optimization' extensions that are being too agressive in combining javascript files
* not having the 'Include jQuery / Bootstrap' setting enabled in the SCLogin module
and various other things

I'd try altering any of the settings above on your site to see if that helps. If not, let us know the URL where we can see the issue and we'll gladly help investigate further.

Thanks,

For optimization, do you have JCH Optimize extension enabled? Also, some templates have optimization or caching settings as well.

If not, please provide a specific URL where we can see the behavior in action/look at the source code and we'll help investigate.
