You also have option of disabling the AjaxUI for modules or across the entire system.
From 6.3 version, SugarCrm have admin section for disabling the AjaxUI on a per module basis (/index.php?module=Administration&action=ConfigureAjaxUI).
It can also be done manually in the config override with a line like:
$sugar_config['addAjaxBannedModules'] = "Acounts";
That would cause links to the Acounts module in SugarCrm no longer attempt to load via the AjaxUI, and use the normal URL structure.
If You want, you have also option of totally disabling the AjaxUI with the following code.
