Conflict of classes with another component

Oops, one more issue found... I am using component for donations called joomdonation. Under (M)Social everything was fine, because there was no class "bar gk-loaded" used in the template there.
Now I have an issue - the bar doesn't show up. You can see it on the screenshot https://yadi.sk/i/bwWfM8O5fAHFE

If I firebug it, and add gk-loaded to that class, the bar will show up https://yadi.sk/i/AcfWUIjUfAHVr. But how do I fix it permanently?

Thanks

Sorry, but this is beyond our support. You can either rewrite our template so it doesn't use that class or 3rd party one.

Well, it's been working with other template of yours, and now it doesn't. So, it is template issue. )))
If Quark "will also receive regular feature and content updates. New additional pages to help round out your content, as well as new features and compatibility to keep the user experience up-to-date" (quote from https://www.gavick.com/joomla-templates/quark), then compatibility is to be considered.
Changing all the styles to totally new naming system is not compatible internally with previous templates. And using styles that are so obvious in naming that any other developer will be using those too - is not helping external compatibility either (as we see in this particular case).
If I change the template, it will be rolled over in the next update, so ain't gonna fly. I'll see how can I change the 3rd party component, since it's not gonna be updated that often (hadn't been for last two years).
Don't take me wrong, Everything that I've said above is not to blame anybody, but to give you some feedback that could be helpful (I hope) for future developments.

Yes, but we cant assure compatibility with each and every joomla plugin that is out there - it is simply impossible.
