In recent months, however, some Sugar customers reported puzzling situations where the Loading... problem could not be resolved through corrections to the rewrite configuration. Adding to the bewilderment was the point that the configuration of these environments seemed to be in order. For example, PHP versions and configuration seemed to line up with recommendations provided by SugarCRM.
If you are encountering the Loading... issue and have already completed the steps to verify and/or correct the potential rewrite issues, double check your version of the JSMin extension. You can check the version by taking a look at the JSMin section of the output from phpinfo().
Should you have version 2.x of JSMin installed, you can correct the problem by:
- Downgrading your version of JSMin to 1.1. Please note that if you are installing via PECL, you will need to specify the version you wish to install or it will install the latest version (2.x). To ensure it installs version 1.1, use the following command: pecl install jsmin-1.1.0
Hope this helps.
