Network subsite title is limited/cut to 50 characters

[theode]

In wpmu_validate_blog_signup of ms-functions.php I can find near Line 600

$blog_title = substr( $blog_title, 0, 50 );

Is there a reason for this?

I did a git blame on the line in question and it's one of the original, unaltered lines from the WPMU merge, so it was originally a restriction in WPMU. Currently in WordPress the title of a blog is stored in a column whose size is LONGTEXT, so there doesn't appear to be a need for the restriction at least from a storage standpoint.

Unless someone has a reason for wanting the limit to remain, when a single site install of WordPress can have a title > 50 characters as is, I'll write a patch to remove this for 4.4.

Thanks again for the report @theode!

Source in MU is ​https://mu.trac.wordpress.org/changeset/1140. Not much explanation there :/

I don't see a problem making the change. Thanks for the ticket and for the patch.

In 34455:

Multisite: Don't limit site titles to 50 chars.

This restriction dates from ye olden times, ie ​https://mu.trac.wordpress.org/changeset/1140.
It is no longer relevant.

Props chriscct7, theode.
Fixes #33973.
