18323	"Screen Options ""Show on Screen [n] Posts"" for custom post type containing digits in its name does not work"	vtowel	ryan	"1. In a plugin, write the code to register a custom post type called ""all_in_1_event"", or any other name that contains a digit.
2. On the manage screen for that custom post type, reveal the Screen Options.
3. Enter a new value for the ""Show on Screen [n] Posts"" field, something other than the default value of 20.
4. Click ""Apply"".
5. Reveal the Screen Options again.
6. The new value has not been saved.

It seems to be that this is because of a check that occurs in the set_screen_options() function (misc.php, line 331). The option name is not allowed to contain digits - only letters, dashes and underscores - and I don't understand why. Our custom post type does contain a digit, and it has never been a problem for us before - except for saving the Screen Options."	defect (bug)	closed	normal	3.5	Post Types	3.2.1	normal	fixed	has-patch	wordpress@… leho@…
