When I opened "/wp-admin/categories.php" I got following error message.

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 3877 bytes) in /path_to_wordpress/wp-includes/category.php on line 369

I made over 70,000 categories manipulating MySQL table directory.

  • Milestone changed from Unassigned to Future Release
  • Severity changed from normal to minor

the only way to fix this is to rework the walker classes, in such a way that they only load what is needed (as is done in Yahoo Mail, for instance).

  • Keywords dev-feedback removed
  • Type changed from defect (bug) to enhancement

What if we had something like

if num_rows * [rough estimate of memory needed per category] > memory_limit then

load only so much


go right ahead

I can't replicate this error - The difference between one byte of assigned memory makes the page either completely fail or completely load.
