Re: Several issues
is it possible to replace the crappy cropping tool of 1.0.3 without upgrading to 1.1
Anything is possible if you have the coding skills. But, your best option is to upgrade to BP 1.1.1.
What is the issue you are having with upgrading? Just theme issues? Or, as you stated above, are you concerned about losing the core file modifications that you’ve made?
You should never–did I say never yet–modify any core files. Instead, make your custom mods in your own plugin file or in bp-custom.php file.
