I was installing SugarChimp-7.11.3-for-Sugar7 it was stuck at 80% I followed the instructions below for stop it wasn't going any where for about 6 min. now all of sugar is crashed.
NOTE: If the installation stops at 80% and you are using Sugar 7.*, go to Sugar > Admin > Search and click "Schedule System Index". When the system index finishes, go back to Sugar > Admin > Module Loader and install SugarChimp again. If it does not install properly, please let us know and we will help.
