I am running joomla on IIS 7.5 and MSSQL, everything seems to be working just fine, but when I install JCE Eqitor from the admin panel it times out and when i check the logs for error this is what i got:
PHP Notice: Undefined index: cache_entries in D:\Joomlawebsite\libraries\joomla\cache\storage\wincache.php on line 147
PHP Warning: Invalid argument supplied for foreach() in D:\Joomlawebsite\libraries\joomla\cache\storage\wincache.php on line 150
I have IUSR permission as well.
