I keep geting this error message on every page request:

Fatal error: Allowed memory size of 167772160 bytes exhausted (tried to allocate 36 bytes) in C:\wamp\www\mydrupal2\includes\theme.inc on line 98
Call Stack

Increasing memory allowance has not had any effects. I try using drush to disable the offending theme or go back to the last working one, it's the same error message. I can't even use drush for anything else. It reports the same error message. I tried the SQL method on this drupal.org page. Same result.

  • Roll back your site from backup, using the backup you created just before you enabled the custom theme. Jun 19, 2014 at 19:07
  • In your message the memory limit is about 160Mb, this is usally too low, have tried incrementing to 512Mb or 1024Mb just to test? If you have disabled the theme using the SQL method linked then your error is not comming form the theme, did you enable any other module before?

  • I think the problem is now from the drupal itself and not the theme. I suggest you clear the cache and restart the server and see if that would help. Jun 19, 2014 at 19:33
  • @FreeRadical I don't have a backup

  • @AhmedJabar I can't do anything on drupal, even with drush. It's always this error message.

1 Answer 1


theme.inc on line 98 is trying to collect theme's ancestors.

My bet is that your custom theme is wrong and it's telling Drupl that is a subtheme of itself, making Drupal the enter in an infinte loop that exhausts memory.

Double check your custom theme configuration or just move it away from Drupal directories so Drupal can't process it.

  • I have moved custom theme directory from drupal installation. Still no luck.
