Fatal error: while enabling AT theme I tried to enable AT theme and now have a white page with the error:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes) in /Applications/MAMP/htdocs/test/includes/theme.inc on line 98

I changed my php.ini memory_limit = 128M. No difference.

I am so crazy pressed for time, this is the worst thing to happen now. How can i fix this?
Please somebody HELP!!!!!

The site is on a localhost.

PS- now i see a different error: 

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes) in /Applications/MAMP/htdocs/test/sites/all/modules/ds/includes/ds.registry.inc on line 554


Drupal 7.2.4
Looks like 128M of memory is still not enough, try more. If that still fails there's probably a memory leak or endless loop somewhere, or a too bloated configuration (e.g. too many fields, trying to debug a structure that has too many entries and so on).
