v1.5.8 was working until I tried to add the delete_capability to [aam] in Config Press.
After that, both Frontend and Backend were completely inaccessible with:
Fatal error: Call to undefined function parse_ini_string() in ~/wp-content/plugins/advanced-access-manager/library/Zend/Config/Ini_Str.php on line 173
I reverted to v1.4 to recover things and then upgraded again to clean v1.5.8 but error immediately returned even though I had deleted all files (maybe it is in the database?).
I am using v1.4 again but it doesn't have a Config Press tab so I can't rectify it.
I read support from v1.5.8 link but going directly to http://www.whimba.org/support, no support is showing.
