 - `CLAY_ERROR_TYPE_TEXT_MEASUREMENT_FUNCTION_NOT_PROVIDED` - The user is attempting to use `CLAY_TEXT` and either forgot to call [Clay_SetMeasureTextFunction](#clay_setmeasuretextfunction) or accidentally passed a null function pointer.
 - `CLAY_ERROR_TYPE_ARENA_CAPACITY_EXCEEDED` - Clay was initialized with an Arena that was too small for the configured [Clay_SetMaxElementCount](#clay_setmaxelementcount). Try using [Clay_MinMemorySize()](#clay_minmemorysize) to get the exact number of bytes required by the current configuration.
 - `CLAY_ERROR_TYPE_ELEMENTS_CAPACITY_EXCEEDED` - The declared UI hierarchy has too many elements for the configured max element count. Use [Clay_SetMaxElementCount](#clay_setmaxelementcount) to increase the max, then call [Clay_MinMemorySize()](#clay_minmemorysize) again and reinitialize clay's memory with the required size.
-- `CLAY_ERROR_TYPE_ELEMENTS_CAPACITY_EXCEEDED` - The declared UI hierarchy has too much text for the configured text measure cache size. Use [Clay_SetMaxMeasureTextCacheWordCount](#clay_setmeasuretextcachesize) to increase the max, then call [Clay_MinMemorySize()](#clay_minmemorysize) again and reinitialize clay's memory with the required size.
+- `CLAY_ERROR_TYPE_TEXT_MEASUREMENT_CAPACITY_EXCEEDED` - The declared UI hierarchy has too much text for the configured text measure cache size.

 - `CLAY_ERROR_TYPE_DUPLICATE_ID` - Two elements in Clays UI Hierarchy have been declared with exactly the same ID. Set a breakpoint in your error handler function for a stack trace back to exactly where this occured.
 - `CLAY_ERROR_TYPE_FLOATING_CONTAINER_PARENT_NOT_FOUND` - A `CLAY_FLOATING` element was declared with the `.parentId` property, but no element with that ID was found. Set a breakpoint in your error handler function for a stack trace back to exactly where this occured.
 - `CLAY_ERROR_TYPE_INTERNAL_ERROR` - Clay has encountered an internal logic or memory error. Please report this as a bug with a stack trace to help us fix these!
